Answer 1

128 ft^2 needed

Explanation:

Given

See attachment for missing details

Required

Determine the number square feet needed

First, calculate the inner area (A1)

`A_1 = Length * Width`

`A_1 = 20ft * 8ft`

`A_1 = 160ft^2`

Next, calculate the outer area (A2)

`A_2 = Length * Width`

`A_2 = 24ft * 12ft`

`A_2 = 288ft^2`

The area of the planter is:

`Area = 288ft^2-160ft^2`

`Area = 128ft^2`

Hence, he needs 128 square feet
