Question 10 options:

-7m

4m

3m

7m

Respuesta :

Reennaa
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
its 3m i just took it and put the answer 4m in and it said it was wrong
