Answer:
Area= 302.86cm^2
Step-by-step explanation:
Small Rectangle:
A= LW
A= 4cm(8cm)
A= 32cm^2
Bigger rectangle:
A=LW
4cm -3cm= 1cm
1cm +11cm= 12cm
8cm -6cm= 2cm
2cm +6cm= 8cm
A= 12cm(8cm)= 96cm^2
Area overlap for rectangles:
A= LW
4cm -3cm= 1cm
8cm -6cm= 2cm
A= 1cm(2cm)
A= 2cm^2
96cm^2- 2cm^2= 94cm^2
Triangle:
A= 1/2LH
6cm +2cm= 8cm
8cm -5cm= 3cm
3cm +8cm= 11cm
A= 1/2(10cm)(11cm)
A= 5cm(11cm)
A= 55cm^2
Circle:
A= pir^2
12cm -6cm= 6cm
6cm +8cm= 14cm
Diameter= 14cm
Radius= diameter/2
R= 14cm/2
R= 7cm
A= 3.14(7cm)^2
A= 3.14(49cm^2)
A= 153.86cm^2
94cm^2 +55cm^2 +153/86cm^2= 302.86cm^2
