Question

A rope 312 m long is twisted to make an equilateral triangle. Find the side of the triangle so formed. Also if the same rope is folded to form a square, find the side and perimeter of the square.​

Answer 1

Step-by-step explanation:

we can say that perimeter of triangle = 312 m

therefore , perimeter of triangle = 3 × l

$= 312 = 3 \times l \\ l = \frac{312}{ 3} = 104m \\ \\ perimeter \: of \: square \: = 4 \times l \\ = 4 \times 104 \\ = 446m$

therefore , length = 104m

perimeter of square = 446m
