Length = l
width = 1/3 of length = l/3
perimeter = 2(l + l/3)
Answer is option B
-----------------------------------
2(l+ l/3) = 56
⇒ 8l/3 = 56
⇒ l = 3*56/8
⇒ l = 21 inch
width = 21/3 = 7inch
Area = 21*7 inch² = 147 inch²
I cant see it that well best of luck
When setting up the equation you have the initial fee and the hourly fee. The hourly fee is what must be multiplied by the number of hours which is our unknown
Since we are working with an equation written in scientific notation and we are dealing with a negative exponent, we are going to divide 4.7 by 10 three times.
4.7 / 10 = 0.47
0.47 / 10 = 0.047
0.047 / 10 = 0.0047
Best of Luck!
