Question

The school is building a new pool with locker rooms. The locker rooms have the same area. What is the total area of the pool and both locker rooms? A) 450 sq ft B) 460 sq ft C) 470 sq ft D) 480 sq ft

Answer 1

Answer:

B) 460 sq ft

Explanation:

The area of a rectangle is computed as the product of length and width. The area of interest here can be decomposed into three rectangles:

... pool: 10 ft × 40 ft = 400 sq ft

... girls: 6 ft × 5 ft = 30 sq ft

... boys: same as girls, 30 sq ft.

Then the total area is the sum of these:

... total area = 400 sq ft + 30 sq ft + 30 sq ft = 460 sq ft
