Let x = the shorter piece and Let y = the longer piece.
(3/4)x = 120
x = 120 / (3/4)
x = 120 * (4/3 = 480/3) = 160 feet
y = 160 + 12
Answer: Area = Length times width
Area = (3w + 7) x w
Area = 3(3 x 3 + 7) x 3 = 48 m^2
Step-by-step explanation:
Area = Length times width
Area = (3w + 7) x w
Area = 3(3 x 3 + 7) x 3 = 48 m^2
Answer:
Part A) The percentage increase was

Michael is financially better off this year than last year
The markup is 150%
126/84= 1.5
1.5 x 100 = 150%
Proof : 1.5 x 84 =126
If the width is 6.5 then double that to work out the two widths which would be 13. Take that from the perimeter so you're left with 21. Half 21 to work out one length which is 10.5. Length = 10.5
