The length of a rectangle is 4 more than its width. The area of the rectangle is 21m2 . What is the measure of the width?

iris [78.8K]

Length(l)= 4+ w
Width(w)=w
Area(A)= 21m^2

so keep in mind Area= Length × width

A= l×w
21=(4+w)(w)
21= 4w+ 2w
21=6w
w=3.5

The width is 3.5m

so the answer is about 4m
