Measurement of garden = 15*20 steps
1 step = 2 feet
Therefore his garden measures 30*40 sq. feet i.e. 1200 sq.feet

MR. Green expects
0.5 pound of potato from 1 square foot
therefore he can expect 600 pounds of potato from 1200 sq. feet of garden.

hence option A

total area of rectangular garden = 15 *2 = 30 feet and 20*2 = 40 feet
so total area = 40*30 - 1200 ft2
potatoes = 0.5 per feet2 or say 0.5 *1200 ; 600

The area of the garden is 30 x 40 = 1200 square feet.

Thus, the garden is expected to produce 1200 x 1/2 = 600 pounds of potatoes.
