Question

The side of an equilateral triangular field is $48m$ . If the perimeter of a square field is equal to the perimeter of this triangular field, then the length of the side of the square field is

• A. $30m$
• B. $48m$
• C. $72m$
• D. $36m$

Answer 1

The correct option is D

$36m$

We have given, the side of the triangular field $=48m$

According to the question,

The perimeter of a square field $=$ perimeter of an equilateral triangular field

$\Rightarrow$$4\times$side of square field $=3\times$ side of triangular field

$4\times$ side of square field $=3\times 48m$

Side of square field $=\frac{144}{4}m$

Side of square field $=36m$
