Answer 1

1) The perimeter of a square is 16. What is the measure of its one side?

→ Let the one side of the square be "x" .

We know that,

→ Perimeter of square = 4 × Side

→ 16 = 4 × Side

→ Side = $\cancel{ \sf { \dfrac{16}{4} }}$

→ Side = 4 units

Henceforth, measure of one side is 4 units.

2) The cost of 3 - kg of rice is 150. Find the cost of 1 kg of rice.

→ Let the cost of 1 kg of rice be x.

→ Cost of 3 kg of rice = Rs 150

→ Cost of 1 kg of rice = Rs $\cancel{ \sf { \dfrac{150}{3} }}$

→ Cost of 1 kg of rice = Rs 50

Henceforth, cost of 1 kg or rice is Rs 50.

3) How many packets of 1- kg each can be made from a bag containing 10 kg?

→ Let the number of packets be "x"

According to the question :

→ Number of packets × 1 kg = 10 kg

→ Number of packets = $\cancel{ \sf { \dfrac{10}{1} }}$ packets

→ Number of packets = 10 packets

Henceforth, 10 packets of 1- kg each can be made from a bag containing 10 kg.

4) How many pieces measuring 3 m can be cut from a ribbon measuring 15 m?

→ Let the number of pieces be "x".

According to the question :

→ 3m × Number of pieces = 15 m

→ 3m × x = 15 m

→ x = $\cancel{ \sf { \dfrac{15}{3} }}$ pieces

→ x = 5 pieces

Henceforth, 5 pieces measuring 3 m can be cut from a ribbon measuring 15 m.

5) One-fifth of a number is 132. Find the number.

→ Let the number be "x".

According to the question :

• $\sf { \dfrac{1}{5} \times Number = 132 }$

→ $\sf { \dfrac{1}{5} x = 132 }$

→ $\sf { x = \dfrac{132}{\cfrac{1}{5} } }$

→ $\sf { x = 132 \times \dfrac{5}{1} }$

→ x = 660

Henceforth, the number is 660.
