Answer:

The answer to your question is Area = 620 m²

Explanation:

Process

Find the area of the different parts of the prism and later added them.

1.- Area of the base

Area of a rectangle = 10 m x 24 m = 240 m²

2.- Area of the lateral sides (there are 2)

Area of a rectangle = 10 x 13 x 2 = 260 m²

3.- Area of the triangles (there are 2)

Calculate the height using the pythagorean theorem

13² = 12² + b²

b² = 13² - 12²

b² = 169 - 144

b² = 25

b = 5

Area = 1/2 (24 x 5) x 2 = 120 m²

4.- Total area

Area = 120 + 260 + 240

= 620 m²
