Question

Q8. A rope 312 m long is twisted to make an equilateral triangle. Find the side of
the triangle so formed. Also if the samerope is folded to form a square, find the
side and perimeter ofthe square.​

Answer 1

Step-by-step explanation:

Let one side of equilateral traingle be 'a' mts

Let one side of the square be 'l' mts

A/Q,

3a = 312m

a = 312/3

= 104m

Each side of the traingle is 104m

4l = 312m

l = 312/4

= 78.5m

Each side of the square is 78.5m

Perimeter of the square is length of the rope = 312m
