Question

you are putting grass down in your backyard. the total area is 51 feet squared. the length of your yard is 10.2 feet. how wide is your backyard

Answer 1

5 feet wide because a=l*w l being length and w being width.

we have 2 parts of the equation: 51=10.2*w so we divide both sides by 10.2 giving us 5=w
