The diagonal of the floor of a rectangular closet is 7
feet. The shorter side of the closet is 4 feet. What is the area of the closet in square feet?
feet. The shorter side of the closet is 4 feet. What is the area of the closet in square feet?
Answer: Option
Explanation:
| Other side | = |
| ft | ||||||||||||
| = |
|
ft | |||||||||||||
| = |
|
ft | |||||||||||||
| = | 6 ft. |
Area of closet = (6 x 4.5) sq. ft = 27 sq. ft.

You correct @Sheela.
By using Pythagoras theory, we can predict.

@Siddhesh.
Breadth i.e. the smallest side is 9/2 ie 4.5 since the area of rectangle is length*breadth therefore the final step is 6*9/2 or 6*4.5

Length of closet will come 12/2 feet. (Using Pythagoras theory).
And area = l*b = (9/2)*(12/2) = 9*3 = 36 sq.feet.
Then how it comes 27 sq.feet?

Using the formula given hy^2=base^2+hgt^2.
We get the ans as 6ft and here in the question we have to find the area in square feet so we have to multiply with 4.5 = 9/2 so we have the ans of 27 with the product of 4.5 and 6 because we are considering the side but not the diagonal.

(Hypotenuse)2 = (Base)2 + (Height)2.
So! H^2 = hy^2 - Base^2 ----- eq1.
Here hy = 15/2 , base= 9/2 ...................(*9/2 = 4.5).
After solve eq1, we get 6ft
Area of closet = 6ft * 4.5 ft (this come from base, see to * ..).
