The base of a triangular prism is a right triangle whose legs are 7 cm and 24 cm. the height of the prism is 30 cm. what is the lateral area of the prism?

Ok, base area: triangle sides are 25cm each, or .25m
s=semiperimeter
area=s(sqrt(s-side)^3)
s=75/2
s-side=37.5-25=12.5
area=37.5*12.5*sqrt12.5
let E6 mean 10^6
.075E6m=1/3 (37.5*12.5*(sqrt12.5))h
solve for h
I get:137cm
I hope that helped

The answer is the first one
