Answer:
132 cm^2
Step-by-step explanation:
Area of the two triangles + Area of the three triangles
2x1/2x3x4 + 5x10 + 4x10 +3x10 = 132 cm^2
The rules used in my answer are:
- Area of the ∆ are Half x Base x Height
- Area of the rectangle Length x Width
To find the area of the triangular faces use the formula A=1/2bh, where A= Area, b=base, and h= height
