Question

The perimeter of a rectangle is 32 feet. Find the dimensions of the rectangle if the length is 4 feet longer than three times the width. Then find the area of the rectangle.

Answer 1

2(x+y)=32
x+4=y

Answer 2

Could you explain? Im confused :P

Answer 3

where x and y are the length and width

Answer 4

use substitution to solve for x and y

Answer 5

So would I do 3x+4=32? 4 more than 3 times the width?

Answer 6

Sorry, I really dont get this stuff.

Answer 7

Oh wait, I get it, nevermind, thank you!

Answer 8

put x+4=y into 2(x+y)=32 to get 2(x+x+4)=32

Answer 9

2(2x+4)=32

Answer 10

after you solve it, substitute x back into one of the equations to solve for y
