20 * 4 = 80 = perimeter of the square 24*2 = 48, the length of two sides of the rectangle. Deducting from 80 we are left with 32 and dividing by 2 we know the rectangle is 24 x 16 Area = L * W, so you can calculate the area of the rectangle.

Answer:
a) 21m - 0.87 = m
b) m = 0.0435 mg
21(0.0435) - 0.87 = 0.0435
0.9135 - 0.87 = 0.0435
0.0435 = 0.0435
True statement, so correct
c) 21m - 0.87 = m
20m = 0.87
m = 0.87/20
m = 0.0435 mg
