Question

Find the perimeter of the rectangle whose L=2x-5 and W=x - 5.

Answer 1

Answer:

The answer is 6x - 20 sq units

Step-by-step explanation:

so from the question,

l = 2x-5  and w = x-5

To find the perimeter,

  perimeter = 2( l + b )

                   = 2( (2x-5) + (x-5))

                   = 2(2x-5) + 2(x-5)

                   = 4x - 10 + 2x - 10

 perimeter  = 6x-20 sq units
