Question

The width of a rectangle is 4 more than half the length.

If the perimeter of the rectangle is 74, what is the width?

Perimeter of rectangle: P = 2l + 2w

Width= ? Length= ?

Answer 1

Answer:

The answer to your question is L = 22; w = 15

Step-by-step explanation:

Data

    length = L

    width = w

    Perimeter = 74

Condition

               w = L/2 + 4

Formula

               P = 2L + 2w

Substitution

               74 = 2L + 2(L/2 + 4)

Simplification

               74 = 2L + L + 8

               74 = 3L + 8

                74 - 8 = 3L

                3L = 66

                  L = 66/3

                  L = 22

                  w = 22/2 + 4

                  w = 11 + 4

                  w = 15
