Answer:
He estimated enough bricks for the patio.
Step-by-step explanation:
We can confirm that Stew ordered enough bricks by taking into account the area of the patio. To deduce the area, we use the formula A=bxh
We know:
b(base) is 12.5 ft
h (height) is 18.3 ft
So, A=12.5ftx18.3 ft
A=228.75 ft²
He ordered enough bricks for the patio. There would be extra bricks since the area is 228.75 ft², and he ordered bricks for 247 ft².
