Question

the perimeter of a rectangular parking lot is 190 meters. the width is one fourth the length. write a system of equation for this scenario

Answer 1

Hello!

You can make 2 equations based on what you know

2l + 2w = 190

w = 0.25l

Put w into the first equation

2l + 2(0.25l) = 190

Distribute the 2

2l + 0.5l = 190

Combine like terms

2.5l = 190

Divide both sides by 2.5

l = 76

Put l into the second equation

w = 0.25(76)

Multiply

w = 19

The length is 76 and the width is 19

The answer is

2l + 2w =190
w = 0.25l

Hope this helps!
