The ratio of similarity of BOY to
GRL is 1:2. If BOY x 3 and GR 3 x
1, then the length of GR is
To find the length of GR, we need to use the given ratio and the information about BOY and GRL.
The ratio of similarity between BOY and GRL is 1:2. This means that if we multiply the length of BOY by a certain factor, we will get the length of GRL.
According to the information provided, BOY is multiplied by 3, and GRL is multiplied by 1. Therefore, we can establish the following equation:
BOY x 3 = GRL x 1
We can simplify this equation to:
3BOY = GRL
Now, since the ratio is 1:2, we can define BOY as x (a variable) and GRL as 2x. Substituting these values into the equation, we get:
3x = 2x
To find x, we can cancel out the x on both sides of the equation:
3 = 2
This equation is not true since 3 is not equal to 2. Therefore, there is no valid solution to this problem, and we cannot determine the length of GR based on the given information.
