Let
L be the length
W be the width
Suppose
L=3w
Our formula for finding the area is L multiplied by the width (A=L*W).
So, firstly we substitute the value of L
Apply division property to isolate
Square root both sides
Where w=1.5
If w is 1.5 then length is 3 times its width which is equal to 4.5
Check
1.5 * 4.5
=6.75
Therefore our width is 1.5 m and length is 4.5m
