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

  • Geometry -

    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

    oops.

    a rhombus has four equal sides
