Question

Find the area of the shaded region if x = 8 inches, y = 10 inches, w = 16 inches, and z = 19 inches.

The area of the shaded region is   square inches

Answer 1

The area of the shaded region is equal to the area of the large rectangle minus the area of the small rectangle.

Answer 2

To be more specific:

the area of a rectangle (A) = length x width

area of shaded region is as follows : the area of entire large rectangle minus the area of the smaller rectangle...

Z x W - Y x X = area of shaded region

Area of large rectangle (length x width) is Z x W = 19 x 16 = 304 inches

Area of small rectangle (length x width) is Y x X = 10 x 8 = 80 inches

Area of shaded region is 304 - 80 inches = 224 inches
