Question

The base of a right prism is a right triangle whose catheters measure 12 cm and 35 cm. Calculate the lateral area of ​​the prism knowing that it is 10 cm high. How can I solve it? ​

Answer 1

Prisms contain rectangles and triangles

Lateral area is calculated as : perimeter of base × perpendicular height

We can take the rectangle as our base

So lateral area will be :

[2 ( 12 + 35 ) × 10]

= 940 $cm^{2}$
