Answer :
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:
The width of the rectangular window is 75 cm.
Solution:
Given,
Area of rectangular window = [tex]6525 cm^2[/tex]
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,
[tex]Area (A) = l \times w[/tex]
From the given, [tex]A is 6525 = 87\times w[/tex]
On solving for w,
[tex]w = \frac{6525}{87}[/tex]
[tex]\therefore w = 75 cm[/tex]
