Step: 1

Given side lengths are 8 and 7

Step: 2

rows = 7 and columns = 8, tiling the rectangle cornfield as below.

Step: 3

Its area, that is number of square yards = rows × columns

Step: 4

= 7 × 8

Step: 5

= 56 square yards

Step: 6

Therefore, the cornfield is 56 square yards.

Correct Answer is : 56 square yards

Step: 1

Window is 11 meters tall and 6 meters wide.
