Answer should be 5(7x-4)
I factored out the greatest common factor which is 5.
Answer:
Length:
11
Width:5
Step-by-step explanation:
Let's say x is the width, then length is 3x-4
Area of a rectangle is Length times width
so x(3x-4)=55
then we solve
3x^2-4x-55=0
(3x+11)(x-5)=0
x cannot be negative so x=5
then if the width is 5, length is 3*5-4=11
184cm2
8x5=40x2=80
4x5=20x2=40
8x4=32x2=64
80+40+64=184cm2
