First you need to know the formula for the Area of a trapizoid which is 1/2*h(b1+b2). The seperate the triangle and use Converse of the pythagorean therom to figure out the other base of the trapizoid and add the other base from the top to it.
Ok first add all of the results together 44+55+55+66=220 Then found out how many percent each number is of 220. 44 is 20% of 220, 55 is 25%, 55 is 25%, 66 is 30%
