Answer:
132 squared cm
Explanation:
Alright so assuming the this is a right angle, to find the area of a triangle you have to multiply LxW and divide by 2. 3x4=12/2=6. There are 2 triangles, so 6x2=12
And then to find the area of the rectangle on the bottom, 10x4=40
Next you find the area of the rectangle on the side: 3x10=30
And finally the one that’s slanted on the top: 5x10=50
Add them up and 12+40+30+50= 132
