The perimeter of a rectangle is 62 feet. The width is seven feet less than the length. Find the length and the width. Show work, please.

The answer to your question is length = 19 and width = 12 ft

Step-by-step explanation:

Data

Perimeter = 62 ft

Width = length - 7

Process

1.- Write equations that help to solve this problem

    Perimeter = P = 2w + 2l

                         w = l - 7

2.- Substitution

                       62 = 2w + 2l           Equation l

                         w = l - 7                 Equation ll

Solve the system of equations by substitution

- Substitute equation ll in equation l

                      62 = 2(l - 7) + 2l

-Simplification

                      62 = 2l - 14 + 2l

                      62 + 14 = 4l

                              76 = 4l

                                 l = 76/4

                                 l = 19 ft

-Find w

                       w = 19 - 7

                       w = 12 ft                                        

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
