I'll tell you how to do them, but I won't do them for you1. the formula for the area of a trapezoid is (base1+base2)(height)/2 so all you do is plug in the numbers2. You know the perimeter is equal to the sum of all the sides, so the equation is 2w+2L=P3. Using the equation from the above problem, the width=x and the length=3x, then solve4. Same problem, width=x, length=6x5. Once again, it is the same deal, width=x12, length=x
