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 a equilateral triangle. The length of their sides must be the same. How should it be cut? ​

Answer 1

Answer:

2meter and 1.5 meter

Step-by-step explanation:

square has 4 equal sides and equilateral triangle has three equal sides. so, we get 4+3 = 7 equal sides.

3.5 metre ÷ 7 = .5 metre

for square, we need = .5 metre × 4 = 2 metre

for equilateral triangle, we need = .5 × 3 = 1.5 metre

Answer 2

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 a equilateral triangle. The length of their sides must be the same. How should it be cut?

ANSWER :-

$3 \frac{1}{2} \div 7$

$3 \frac{1}{2} = \frac{7}{2} \div 7$

$\frac{ \frac{7}{2} }{7} = \frac{7}{2 \times 2} = \frac{7}{14} = \frac{1}{2} cm$

Length of the rod for the square

$= 4 \times \frac{1}{2} = 2m$

Length of thr for the quadrilateral triangle

$= 3 \times \frac{1}{2} = 1 \frac{1}{2} m$
