Answer:
Percent means per- amount
And the second one is dividing.
Step-by-step explanation:
Answer:
Replace l with 110 and w with 120
P = 2(110) + 2(120)
P = 220 + 240
P = 460 feet
Let width = x ft then
2x + 2(2x) = 42
6x = 42
x = 7
so the width is 7 ft and length is 14 ft.
So the cost to build the pen = 14*1.25 + 14*1,25 + 7*2.50 + 7*2.50
= 70 answer
