How do you find the length of a rectangle with the area?
To find Length or Breadth when Area of a Rectangle is given
- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.
How do I find the length and width of a rectangle if I have the area?
To calculate the length and width of a rectangle first, calculate the value of width ‘w’ by using the area of rectangle formula that is, ‘w = A/l’.
What is the greatest area you can make with a rectangle that has a perimeter of 24 units?
With a perimeter of 24 units the greatest area that can be enclosed is that of a square of 24/4 or 6 units sides. Its area will be 36 sq.
What is area of the rectangle?
In other words, the area of a rectangle is the product of its length and width. That is, A = l x w where l is the length and w is the width of the rectangle. For example, the area of a rectangle of length 35 m and width 25 m is 35 times 25 or 875 square meters. The area of the carpet is equal to the area of the room.
How do you find the greatest area of a rectangle?
A rectangle will have the maximum possible area for a given perimeter when all the sides are the same length. Since every rectangle has four sides, if you know the perimeter, divide it by four to find the length of each side. Then find the area by multiplying the length times the width.
What is the greatest area of a rectangle?
Approach: For area to be maximum of any rectangle the difference of length and breadth must be minimal. So, in such case the length must be ceil (perimeter / 4) and breadth will be be floor(perimeter /4). Hence the maximum area of a rectangle with given perimeter is equal to ceil(perimeter/4) * floor(perimeter/4).
How do you find dimensions of a rectangle?
Find the dimensions of the rectangle using the perimeter. For this example, suppose the perimeter is 22 feet and the length is 5 feet. Write down the perimeter equation for a rectangle: P = 2L + 2W where “P” stands for perimeter, “L” stands for the length and “W” stands for the width.
What is the dimension of rectangle?
A rectangle has two dimensions: we can measure its length and, perpendicular to that, its width. The interior of a triangle or oval is also two-dimensional.
What is the area of the rectangle whose length and width?
Thus, the area of the rectangle = Length x Breadth. Solved Examples. Example 1: Find the area of the rectangle whose length is 15 cm and the width is 4 cm. Solution: Given, Length = 15 cm. Width = 4 cm. Area of a rectangle = Length × Width. 15 × 4 = 60. So the area of rectangle = 60 cm 2
What is the formula to find the perimeter of a rectangle?
To find the perimeter of rectangle we add the lengths of its sides. Thus, the perimeter of a rectangle with the length of a a and the width of b b is P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b) P = a + b + a + b = 2 × a + 2 × b = 2 × (a + b)
What is the difference between a rectangle and a square?
It is to be noted that in a rectangle the opposite sides are equal in length which makes it different from a square. For example, if one side of a rectangle is 20 cm, then the side opposite to it is also 20 cm. A rectangle is characterized by length (L) and width (W).
How do you calculate square feet for a rectangle?
For example, a garden shaped as a rectangle with a length of 10 yards and width of 3 yards has an area of 10 x 3 = 30 square yards. A rectangular bedroom with one wall being 15 feet long and the other being 12 feet long is simply 12 x 15 = 180 square feet.
