- In the line 2, only variables were operated with a reduction of similar terms in each side of the equation, giving as result -4x at one side, and 2x at the other side.
- In the line 3, terms with variables were joined together in one side of the equation, and then, they were operate it, given as result -6X.

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
