Answer 1

The recommended dimensions for the garden is as follows:

Length 1 = Length 2 = 20 feet

width 1 = width 2 = 5 feet

depth 1 = 1.5 feet

depth 2 = 3 feet

Given data

The garden should be at least 200 square feet for the for the plants

The volume should be less than 500 cubic feet

How to get the are at least 200 cubic feet

The area of the garden available should be the top of both levels

say the top has equal widths of 5 and the length is 20

therefore area of the two levels will be

= area of level 1 + area of level 2

= L1 * B1 + L2 * B2

= 20 * 5 + 20 * 5

= 100 + 100

= 200 square feet

condition one: the garden should be at least 200 square feet for the plants is maintained.

volume of the platform

The platform has two levels representing two depths say  3 for the higher level and 2 for the lesser level.

Using the same division used for area and adding them together we find the volume as follows:

= volume of level 1 + volume of level 2

= L1 * B1 * D1 + L2 * B2 * D2

= 20 * 5 * 1.5 + 20 * 5 * 3

= 150 + 300

= 450 cubic feet

condition two: the garden should be less than 500 cubic feet for the platform is maintained
