Question

An equialteral triangle and square have same perimeter x. The difference of length of their sides is given by :

• A. 0,
• B. $\frac{x}{12}$
• C. $\frac{x}{4}$
• D. $\frac{x}{3}$

Answer 1

Perimeter of a triangle = x
$Side=\frac{x}{3}$ (As there are 3 equal sides in an equilateral triangle)
Perimeter of a square = x
Side of square= $\frac{x}{4}$ (As there are 4 equal sides in a square)
Difference in the sides= $\frac{x}{3}-\frac{x}{4}$
= $\frac{x}{12}$
