[tex]===========================================[/tex]
Formulas:
Area of a rectangle/square:
[tex]A=lw[/tex]
Area of a triangle:
[tex]A=bh\frac{1}{2}[/tex]
[tex]===========================================[/tex]
Square:
5*5= 25 cm.
Rectangle#1:
4*5= 20 cm.
Rectangle #2:
3*5= 15 cm.
Triangle (2):
[tex]3*4*\frac{1}{2}=6[/tex]
Multiply by 2 because there are 2 triangles
6*2= 12 cm
Total:
Add them all up.
25+20+15+12= 72
