Question

Find the perimeter and area of isosceles trapezoid EFGH.
A=1/2(b1+b2)•h

Answer 1

We have a height of 4, bottom base of 8, top base of 6, so

A = (1/2)(8+6)(4) = 28

Perimeter, we have sides that are hypotenuses of a right triangle, legs 1 and 4,

s = √(1²+4²) = √17

So perimeter is

P = 8 + 6 + √17 + √17 = 14+ 2√17

Answer: Area 28, perimeter 14 + 2√17
