Question

If the ratio of areas of two equilateral congruent triangles of side length equal to 7 cm is $\frac{\text{x}}{\text{y}}$, then find the value of x + y?[$\frac{\text{x}}{\text{y}}$ is a simple ratio]

• A. 2

Answer 1

The correct option is A 2
Since, the two triangles are congruent they overlap each other or in other words, they have the same area.
So, the ratio is 1 : 1.

This is given in question as $\frac{\text{x}}{\text{y}}$. So, x = 1 and y = 1. Don't misintrepret that $\frac{\text{x}}{\text{y}}=\frac{1}{1}$ always implies x = 1 and y = 1 but imples in the case of simple ratio.
$\text{x}+\text{y}=2$
