Question

Find the area of the lateral faces of the right triangular prism with altitude of 5 cm and base edges of length 3 cm, 4 cm, and 5 cm.

Answer 1

we know that
area of lateral faces of the right triangular prism=perimeter of base*height

perimeter of the base=[3+4+5]----> 12 cm
height of the prism=5 cm
so
area of lateral faces of the right triangular prism=12 cm*5 cm---> 60 cm²

the answer is
60 cm²
