You can put this solution on YOUR website! A rectangular garden is enclosed by a brick border.
The total length of bricks used to enclose the garden is 42 meters.
If the length of the garden is twice the width, what is the area of the garden?
:
This is just a perimeter problem
2L + 2W = 42
Simplify, divide by 2
L + W = 21
:
Then it says,"length of the garden is twice the width,"; therefore
L = 2W
:
Replace L with 2W
2W + W = 21
3W = 21
W = 7 meters is the width
:
I'll let you find the length, multiply that by the width to find the area
