Answer:
620 cm^2
Step-by-step explanation:
Area of isosceles triangles:
A = (b×h) ÷ 2
Substitute
(24 × 5) ÷ 2
120 ÷ 2 = 60 cm^2
There are 2 triangles so:
60 × 2 = 120 cm^2
Area of 2 identical rectangles:
- They are identical and this is shown by the two short lines which indicates that this is an isosceles triangle. They have 2 identical sides.
A = L × W
Substitute
10 × 13 = 130
Because there are two:
130 × 2 = 260 cm^2
Area of rectangle at the bottom:
- Lets not forget the rectangle at the bottom of this shape.
A = L × W
Substitute
24 × 10 = 240 cm^2
Add these all together to get the total surface area:
120 + 260 + 240 = 620 cm^2
Answer: 620 cm^2
