Question

A three and a half metre long rod is to be cut into two pieces, one piece
is to be bent into a square and the other into an equilateral triangle. The
length of their sides must be the same. How should it be cut?​

Answer 1

Answer:

Step-by-step explanation:

LEngth of the rod = 3.5 m = 350 cm.

Length of the sides = x for square and the triangle.

Perimeter of square = 4x.

Perimeter of equilateral triangle= 3x.

7x = 350, or

x = 50 cm

The 350 cm-long rod must be cut into two pieces of 200 cm and 150 cm.
