Answer 1

Correct question: Hassan built a fence around a square yard. It took 500 square feet of lumber to build the fence. The fence is 5 feet tall. What is the area of the yard inside the fence?

Solution:

Given that, the fence is x feet long.

Then its area is = x * 5 = 5x square feet

By the given condition,

5x = 500

or, x = 100

So the fence is 100 feet long and thus each side of the square yard is 100 feet long.

Therefore the area of the yard inside the fence is

= 100 * 100 square feet

= 10000 square feet.
