A trapezoid has a perimeter of 117cm. The two shortest sides have the same length. The third side is 12 cm longer than one short
side. The final side is 9cm less than three times one short side. How long is each side of the Trapezoid? Pls pls help I need an answer, I have to finish this in 15 mins, this is really hard and I will give you 30 points :)
Let the short side be x. 2x+(x+12)+(3x-9)=117 6x-3=117 6x=120 x=120/6=20 Each of the short sides is 20, the third side is 32, and the last side is 51. Hope this helped!
