Question

The perimeter of a rectangular field is 312 yards. If the length is 91 yards, what is its width?

Answer 1

Any ideas?

Answer 2

Perimeter means the distance around the rectangle.

$$\Huge Perimeter =2•length+2•width$$

Answer 3

so..2*315?

Answer 4

you there?

Answer 5

Yes I am

Answer 6

so the perimeter is the length of the sides added up

Answer 7

We have 2 sides which are 91 in length

Answer 8

91+91=182

Answer 9

So the width is 182?

Answer 10

we are looking for 2 sides which have the same length

Answer 11

no

Answer 12

we will use x to represent the unknown width

Answer 13

Since there are 2 of the sides with the same length for the width, we will call it 2x

Answer 14

so the equation is
312 = 182 + 2x

Answer 15

now just solve for x

Answer 16

x=100?

Answer 17

oops

Answer 18

nope, try and solve the equation

Answer 19

what would be the first step?

Answer 20

65?

Answer 21

312=182+2x, what I did was I subtracted 182 from 312 and got 130 and 130/2 = 65

Answer 22

that's correct, good job
