Apiece of string is 36 cm long. What will be the length of each side, if it is used to form : Class 6

Question 1.

Apiece of string is 36 cm long. What will be the length of each side, if it is used to form : Class 6

(а) A square,

(b) A triangle with all sides of equal length, and

(c) A hexagon (a six sided closed figure) with sides of equal length?

Solution:

(a) For square, length of the side

= [latex]\frac{36 \mathrm{~cm}}{4}[/latex] = 9 cm

(b) For triangle, length of the side

= [latex]\frac{36 \mathrm{~cm}}{3}[/latex] = 12 cm

(c) For hexagon, length of the side

= [latex]\frac{36 \mathrm{~cm}}{6}[/latex] = 6 cm

Question 2.

A farmer has a rectangular Held having length 230 m and breadth 160 m. He wants to fence it with 3 rounds of rope as shown (figure given in textbook). What is the total length of rope needed? Class 6

Solution:

Perimeter of the field = 2(230 + 160) m = 780 m.

So, length of rope needed for fencing 1 round = 780 m.

Hence, length of rope needed for fencing 3 rounds = 3 × 780 m = 2340 m.
