Please look a the pic

also you need to find the area

area of circle is 113.04 (i used 3.14 for pi) 3.14 x 6^2

area of square is 24 - 12 x 2 = 24

area of square without circle is 89.04 - 113.04 - 24 = 89.04

Step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
