Use the formulas for the lateral area of a prism.
256.3cm^2
The given solid is a prism.
To calculate the lateral area of a prism, we can use the known formula where P is the perimeter of the base and h is the height. L=Ph We are given two lengths of the base's sides, a= 7 and b= 8. The base of a given prism is a right triangle, so we can use The Pythagorean Theorem in order to calculate the missing length.
a= 7, b= 8

sqrt(LHS)=sqrt(RHS)
Now, let's add these three side lengths to find the perimeter of the base. P&=7+8+sqrt(113) P&=15+sqrt(113)cm Now we have enough information to find the lateral area of the prism. Let's substitute 15+sqrt(113) and 10 for P and h, respectively.
P= 15+sqrt(113), h= 10
