surface area i believe

2. Romero

Well ok you can do several things. One way is to split the shape into smaller shapes. From just looking at it I can split it up to 2 rectangles and 1 triangle and I can find those areas and add them up.

4. Romero

Can you show your work I think you got it wrong.

20. Romero

Nope the area of a triangle is $\frac{1}{2}*b*h=area \triangle$

21. Romero
