Question

Consecutive sides of a rhombus measure 2x + 15 and 4x - 5. What is the perimeter of the rhombus?
a.) 10
b.) 35
c.) 70
d.) 140

Answer 1

a rhombus equal sides, so any two sides are equal.

So,

2x + 15 = 4x - 5
2x = 20
x = 10

so, the sides measure 35 each.
The perimeter is 4*35 = 140

Answer 2

oops.

a rhombus has four equal sides
