Question

Write a formula that will give the area of the shaded region in the figure below .

Answer 1

a=(29-2)*(12-3)

Explanation:

a=LW

a=(L-2)*(W-3)

a=(29-2)*(12-3)

a=27*9

a=243ft²

Answer 2

`\Large \boxed{A = (29 - 2) * (12 - 3)}`

Explanation:

The length of the whole rectangle is 29 feet.

The width of the whole rectangle is 12 feet.

The length of the shaded region is 2 feet less than the length of the whole rectangle.

The width of the shaded region is 3 feet less than the width of the whole rectangle.

The area of a rectangle is length × width.

So we can create a formula to solve for the area of the shaded region:

A = (29 - 2) × (12 - 3)

Solving for the area.

A = 27 × 9

A = 243

The area of the shaded region is 243 feet².
