Answer:
Step-by-step explanation:
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
Bringing like terms on one side
3 + 9 = 4.5x - 1. 5x
12 = 3x
12/3 = x
4 = x
Alright, so let's make the length x and the width y. 2y=x, and xy=area. 2x+2y=perimeter. Plugging 2y=x into the perimeter equation, we get that 3x=perimeter=126, and x=126/3=42
Length=42ft, width=21ft
Answer:
Step-by-step explanation:
area =l^2
=7^2
