A rectangle has a lt of 4.5 inches and a wideth of 3 inches how would the area change if you doubled both dimensions?
Gbrimah
The area before would be 13.5 in2. When the length and width are doubled, the new length is 9 inches and the new width is 6 inches, giving the new rectangle an area of 54 in2. Subtract 13.5 from 54, giving you 40.5, which is the difference and the change of the area.
Work
A=lw
A=(4.5 in)(3 in)
A=13.5 in2
A=lw
A=(9 in)(6 in)
A=54 in2
