Problema Solution
Candice is looking at her plants. In order to fit all in the field ,width must be 10 meters more than four times the length and the perimeter of the field must be at least 140 meters. What it the area of the field?
Answer provided by our tutors
Let X be the width and Y be the length
Equation 1:
X = 4Y + 10
Equation 2
2X + 2Y = 140
2(4Y+ 10) + 2Y = 140
8Y + 20 + 2Y =140
10Y = 120
Y = 12
Substiture Y = 12 to Equation 1
X = 4(12) + 10
= 58
Hence, width is 58 and length is 12
