The length of a rectangle is equal to triple the width. Which system of equations can be used to find the dimensions of the rect
angle if the perimeter is 86 centimeters
1 answer:
Answer:
w=10.75 l=32.25
Step-by-step explanation:
So if we know that the length is 3 times as long as the width than if the width is x, length would be 3x.
3x+3x+x+x=86 There are two lengths and two widths
8x=86 Combine like terms
x=10.75 divide both sides by 8 and our width is 10.75
Length is 32.25 multiply 10.75 by 3
