Answer:
Area = 35 sq cm
Step-by-step explanation:
You've got a little house-like shape here. So you can find the area of the "roof"; it's a triangle. Then find the area of the "building" part; it's a rectangle. Then you just add the two parts together.
"Roof"
Area of a triangle is:
A = 1/2 b•h
= 1/2 •10•3
= 15 sq cm
"Building"
Area of rectangle:
A = l×w
= 10×2
= 20 sq cm
Area = 15 + 20
= 35 sq cm
