Question

The length of a rectangle is twice its width.
If the perimeter of the rectangle is
42

ft
, find its area.

Answer 1

Okai think like this
The width of the rectangle is X
Then the length would be 2X right?

Answer 2

right

Answer 3

yes

Answer 4

what do you guys think is next?

Answer 5

then we know the perimeter of a rectangle includes 2 sides of the length and 2 sides of the width right?

Answer 6

you where correct @peachpi i am sorry i got carried away i looked at a closed question and saw that you where correct

Answer 7

that means the perimeter = length *2 + width *2
So 42= 2x*2 +x*2= 4x + 2x = 6x
if 6x = 42
then x= 42 divided by 6
therefore X= 7 ft right?

Answer 8

@peachpi i need your help

Answer 9

now we know X , That is width
If width = 7ft
Then length = 7*2 ft= 14ft right?

Answer 10

please listen to me @peachpi i am sorry

Answer 11

now we know both the length and the width now its just the matter of calculating the Area
Area = length * width
So Area= 7ft * 14ft = ?
U find that LOL :)
