Question 1038017
"A rectangulat garden has an area of 36m2. How much femcing would be needed to surround the gardens permeter if the length of the garden is three times larger than the width?"
-----------------
1 time greater = 2x as great
2 times greater = 3x as great
3 times greater = 4x as great
====================
L = W + 3W = 4W
L*W = 36
----
Sub for L
4W*W = 36
W^2 = 9
W = 3, L = 12
----
Perimeter = 2W + 2L
= 30 meters
