Question

Write an expression that gives the area of the shaded region in the figure.

Answer 1

(15 ft - 4 ft) * (14 ft - 6 ft)

Explanation:

The shaded area is a rectangle.

area of rectangle = length * width

Length of outer rectangle = 15 ft

Length of shaded rectangle = 15 ft - 4 ft

Width of outer rectangle = 14 ft

Width of shaded rectangle = 14 ft - 6 ft

Area of shaded rectangle = length * width = (15 ft - 4 ft) * (14 ft - 6 ft)

Answer 2

The mathematical expression is : (15 - 4) x (14 - 6) square feet.

The evaluation of this expression gives 88 sq ft.

Explanation:

The length of the shaded region is (15 - 4) feet

The width of the shaded region is (14 - 6) feet

hence the expression for area is

(15 - 4) x (14 - 6) square feet.

fyi, if you work this out, you will get

(15 - 4) x (14 - 6)

=11 x 8

= 88 square feet.
