Perimeter means the distance around the rectangle. $$\Huge Perimeter =2•length+2•width$$

so the perimeter is the length of the sides added up
anonymous
  • anonymous
We have 2 sides which are 91 in length
anonymous
  • anonymous
91+91=182
anonymous
  • anonymous
So the width is 182?
anonymous
  • anonymous
we are looking for 2 sides which have the same length
anonymous
  • anonymous
no
anonymous
  • anonymous
we will use x to represent the unknown width
anonymous
  • anonymous
Since there are 2 of the sides with the same length for the width, we will call it 2x
anonymous
  • anonymous
so the equation is 312 = 182 + 2x
anonymous
  • anonymous
now just solve for x
anonymous
  • anonymous
x=100?
anonymous
  • anonymous
oops
anonymous
  • anonymous
nope, try and solve the equation
anonymous
  • anonymous
what would be the first step?
anonymous
  • anonymous
65?
anonymous
  • anonymous
312=182+2x, what I did was I subtracted 182 from 312 and got 130 and 130/2 = 65
