Answer: 0.555
Step-by-step explanation:
Given:
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm.
The height of the prism is 20 cm.
To find:
The surface area of a triangular prism.
Solution:
We know that, the area of a triangular prism is
Where, P is the perimeter of the triangular base and h is the height of the prism.
The sides of the right triangular base measures 9 cm, 12 cm and 15 cm. So, the perimeter of the right triangular base is
Now, the area of the triangular prism is
Therefore, the surface area of a triangular prism is 720 square centimetres.

Answer:
88 units^2
Step-by-step explanation:
The area of a trapezoid is equal to , where a and b are the top and bottom of the trapezoid and h is height.
We can see that a (top) equals 17, and b (bottom) equals 5 + 17 + 5 = 27. Then, the height of the trapezoid is 4.
Therefore, the answer is 88 units^2.
