Answer 1

500 is your answer.

Explanation:

First solve the length of side BC, CD, EF and FA Since BC = CD = sqrt( 10^2 + 10^2) BC = CD = 14.1421

FA = EF = sqrt(10^2 + 20^2) = 23.3607

So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607 = 93

The area is made up be triangle FAE, rectangle ABDE and triangle BCD

A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)

A = 500 sq units
