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.

How 4.5 came ?

Closet only means a closed space. So here in a rectangle diagonal=7. 5 feet and breadth=4. 5 feet. So using hypotenuse2=base2+altitude2 we can easily find the lenght. So area= l*b.

Shorter side( width) = 4 1/2 = 9/2= 4.5
other side(length) = 6
Area= 6*4.5 = 27
other side(length) = 6
Area= 6*4.5 = 27

Please give the answer for how 4.5 came?

@Siddhesh.
In the question itself one of the side value is given that is 4*1^2 (shortest closet). Since it s shortest closet we are taking that as breadth value 4.5 feet and derived value as the length (6 feet).

What is the shape of closet?

(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 * ..).

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.
