Answer 2

B) 460 sq ft

Step-by-step 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
