Question

The perimeter of parallelogram ABCD is 94 cm. AD is 2 cm more than twice AB. Find the lengths of all four sides of ABCD

Answer 1

AD is 32, BC is 32, AB is 15, CD is 15

Explanation:

2x + 2y = 94

x - 2y = 2

3x = 94 + 2 > 3x = 96 > x = 32

2y = x - 2

2y = 32 - 2 > 2y = 30 > y = 15

y= 15 (The shorter sides)

x= 32 (The longer sides)
