Question

Stu is laying brick down to make a patio. He plans for the patio to be 12.5 feet by 18.3 feet. He orders enough brick for 247 square feet. Which statement about the amount of brick is correct?

Answer 1

Stu estimated correctly by rounding up. He ordered enough brick. The exact is 228.75 square feet.

Answer 2

Stu estimated correctly by rounding up.

He ordered enough brick.

The exact area is
`228.75` square feet

Explanation:

we know that

the area of the patio is equal to

`A=bh`

In this problem we have

`b=12.5\ ft, h=18.3\ ft`

substitute in the formula

`A=12.5*18.3=228.75\ ft^(2)`

`228.75\ ft^(2)< 247\ ft^(2)`
