the length is 2.4

1.2 times 2 to take away the both width sides
minutes 2.4 from 7.2 you get 4.8 then divide by two because it’s a rectangle it has to length side and you get 2.4

Answer:l=2.4ft

Step-by-step explanation:

Perimeter=2(l+b)

7.2=2l +2b

7.2= 2l +2*1.2

7.2=2l +2.4

2l = 7.2-2.4=4.8

l=4.8/2=2.4ft
