Question

The area of a rectangular window is 6525cm2. If the length of the window is 87cm, what is its width?

Answer 1

The formula for a rectangle is A= length*width and we know the area is 6525cm^2 and the length is 87cm. So the equation can be 6525= 87*L and we want to find the length by isolating L. We divide both sides by 87 and get 75. The final answer is 75cm

Answer 2

The width of the rectangular window is 75 cm.

Solution:

Given,

Area of rectangular window =
`6525 cm^2`

Length of the rectangular window = 87 cm

To find: The width of the window

Assume length as l; width as w and area as A.

The formula for the area of a rectangle,

`Area (A) = l * w`

From the given,
`A is 6525 = 87* w`

On solving for w,

`w  = (6525)/(87)`

`\therefore w = 75 cm`
