Question

take out the perimeter of rectangle
length=2 m 25 cm and 1 m 50 cm

Answer 1

Answer:

Length of rectangle = 2 m 25 cm=225 cm

breadth = 1 m 50 cm =150 cm.

perimeter of a rectangle =2(l+b)

=2(225+150)

=2(375)

perimeter of rectangle =750 cm = 7 m 50 cm.

Answer 2

✿ Correct question ✿

Find the perimeter of the rectangle whose length = 2m 25cm & breadth = 1m 50cm

✿ Given ✿

• Length = 2m 25cm
• Breadth = 1m 50cm

✿ We need to find ✿

• Perimeter of rectangle = ?

✿ Solution ✿

As we know that ,

Perimeter of rectangle = 2( l + b )

Where ,

• l → length of rectangle = 2m 25cm
• b → breadth of rectangle = 1m 50cm

Substituting we have ,

⇒ Perimeter = 2( 1m + 50cm + 2m 25cm )

⇒ Perimeter = 2( 3m 75cm )

Converting 3m + 25cm to cm

Substituting 1m = 100cm

→ 3(100) + 75cm

→ 300 + 75 cm

→ 375 cm

⇒ Perimeter = 2(375cm)

⇒ Perimeter = 750 cm = 7m 50cm

Hence , perimeter of rectangle = 7m 50cm
