Question

It took 16 lb of grass seed to cover the field on the left. How many pounds will be needed to cover the field on the right?

Answer 1

432 lb

Explanation:

Find the area of the first square:

40*50=200ft^2

Find the area of the larger square:

60*90=5400 ft^2

Now divide the larger square area by the smaller square area:

5400/200 =27

27 is the ratio of the difference

27*16=432 lb
