There is a rectangular lot in the garden, with 10 ft in length and 4 ft in width. You plan to expand the lot by an equal length around its

four sides, and make the area of the expanded rectangle 72 ft². How long should you expand the original lot in four directions?

You should expand the original lot by blank in four directions. Please type ft to represent feet.

Answer:

You should expand the four sides of the original lot by 2 ft.

Explanation:

10 x 4 = 40

72 - 40 = 32

32/4 = 8

10 - 8 = 2

10 + 2 = 12

4 + 2 =6

12 x 6 = 72
