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 rod =3.5m=350 cm

length of sides =x for square and the triangle

p of square=4x

p of triangle=3x

7x=350

x=50

the 350 cm long rod must be cut into 2 pieces of 200 cm and 150 cm

hope it helps

Answer 2

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

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