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

B) 460 sq ft

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

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
