find the surface area of isosceles trapezoid prism with given
height and
length
The surface area
+
=Lateral Surface Area= the sum of the areas of each surface around the base.
Substitute each piece into the equation:
Simplify:
Distribute and Rearrange:
given that trapezoid is ,so the legs are congruent by definition and
to find use right triangle with one leg , other leg half of difference between bases, and hypotenuse is
leg half of difference between bases:
=>
and, surface area is:
