Parallelogram

The perimeter of the parallelogram is 190 cm. The length of one side is 1.3-times longer than the length of the shorter side. What is the length of the sides of a parallelogram?

Correct answer:

a =  41.3043
b =  53.6957

Step-by-step explanation:


2(a+b) = 190; b = 1.3 a

2·(a+b) = 190
b = 1.3·a

2a+2b = 190
1.3a-b = 0

Row 2 - 1.3/2 · Row 1 → Row 2
2a+2b = 190
-2.3b = -123.5


b = -123.5/-2.3 = 53.69565217
a = 190-2b/2 = 190-2 · 53.69565217/2 = 41.30434783

a = 950/23 ≈ 41.304348
b = 1235/23 ≈ 53.695652
