Answer 4

@Midnight1018 yes I do. I need how they got the answer, but step by step so its easy for me to understand.

Answer 5

Ok, let me look at the problem

Answer 6

Basically, these are the steps. Just plug in the Numbers and variables.
Area left over = Area of Rectangle - Area of Circle

Area of rectangle = (7x)(6x) = 42x2
Area of circle = π⋅r2=π(2x)2=4πx2

so
Area left over = 42x2−4πx2
