25. Nasreen bought 3 m 20 cm cloth for her shirt and 2 m 5 cm cloth for her trouser. Find the
total length of cloth bought by her.
26 The area of a rectangular garden 50 m long is 300 som Find the width of the garden​

Answer 1

Cloth for shirt =3 m 20 cm

Cloth for trouser =2 m 5 cm

Total length of cloth is

3.20

+2.05

5.25

Hence, the total length of cloth bought by her is 5.25 m.

Answer 2

Solution 1:-

☆Total length = length of shirt + length of trouser

⇛ 3 m 20 cm + 2 m 5 cm

⇛ (3 m + 20 cm) + (2 m 5 cm)

⇛ (3 m + 2 m) + (20 cm + 5 cm)

⇛ 5 m + 25 cm

⇛ 5m 20cm

⠀

• Converting to decimals

⠀

⇛ 5 m + 25 cm

⇛ 5 m + 25 × 1 cm

⇛ 5 m + 25 cm × 1/100

⇛ 5m + 25/100

⇛ (5 + 25/100)m

⇛ (5 × 100 + 25/100)m

⇛ 500 + 25/100

⇛ 525/100

⇛ 5.25 cm

⠀

Hence,

• the total length is 5.25 cm.

⠀

Solution 2:-

☆Area of rectangle = l × b

⇛ 300 = 50 × b

⇛ 50b = 300

⇛ b = 300/50

⇛ b = 6 m

⠀

Hence,

• the breadth of the rectangular garden is 6 m.
