Question

The formula for the perimeter of a rectangle is given as P = 2(l + w). Rewrite the equation so that the length is a function of the width and the perimeter, then find the length when the Perimeter is 20 and the width is 4. Length =

Answer 1

length is 6

Explanation:

2(l+4)=20

2L + 8 =20

2L=20-8

2L=12

L=6
