Question 1032397: The perimeter of the rectangle is 78 units. Find the length of side AD. Write your answers in variables.
Side AB equation: 4z+3. Side BC equation: 3z+1 Answer by ewatrrr(24785) (Show Source):
Hi
AB = AND BC =
Find the length of side AD
AB = CD AND BC = AD
AB + BC + CD + AD = 78 + + + = 78
14z + 8 = 78
14z = 70
z = 70/14
AD = 3z + 1
AD = 210/14 + 1 = 16 Units
checking!! AB = CD = = 23
23 + 16 + 23 + 16 = 78
