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
