Look at image for question
Solnce55 [7]

Answer:

1254.24

Step-by-step explanation:

Total area = sum of area of half circles and square

Area of square = 576

Area of half circles = 216π

So total area 576 + 216π

It says use 3.14 for π

So we get total area = 576 + 216(3.14)

==> multiply 216 and 3.14

total area = 576 + 678.24

==> add 576 and 678.24

total area = 1254.24
