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 sq
DedPeter [7]
<u><em>Answer:</em></u>
A: Stu estimated correctly by rounding up. He ordered enough brick. The exact area is 228.75 square ft

<u><em>Explanation:</em></u>
<u>Since the patio is a rectangle, therefore, we can get the area as follows:</u>
area = length * width
area = 12.5 * 18.3
area = 228.75 ft²

<u>Now, Stu rounded up the values, this means that for Stu's calculations:</u>
the length = 19 ft (rounding up the 18.3 ft)
the width = 13 ft (rounding up the 12.5 ft)
calculated area = 19 * 13 = 247 ft²

We can conclude that Stu was correct when he rounded up as he has ordered enough brick to cover the patio

Hope this helps :)
