Step-by-step 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
