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
