Question

The perimeter of the rectangle below is 130 units. Find the length of side VY.

Write your answer without variables.
Y
4y
V
5y + 2
X
W
VY

Answer 1

VY = 28 units

Explanation:

the perimeter (P) of a rectangle is calculated as

P = 2 ( length + breadth )

given P = 130 , then

2(5y + 2 + 4y) = 130 ( divide both sides by 2 )

9y + 2 = 65 ( subtract 2 from both sides )

9y = 63 ( divide both sides by 9 )

y = 7

Then

VY = 4y = 4 × 7 = 28
