What is the area of the composite figure?
(6π + 4) cm2
(6π + 16) cm2
(12π + 4) cm2
(12π + 16) cm2

I hope this helps you

in this figure there are 3 semi circle and one square, one semi circle radius is 2 , square all sides 2.2=4

one semi circles area =pi.r²/2

one semi circle area = pi.2²/2=2.pi

three semi circle area =3.2.pi =6.pi

square area = 4² =16

area of composite figure = 6.pi+16

4x 20 is 80 but if ther machine is broken then there is none you have to redo the test
