1.	A room is 7 m 80 cm long and 5 m 20 cm broad. By how much is the roomlonger than its breadth?
Answer» Answer: 260cm Step-by-step explanation: FIRST convert the length and BREADTH into same units. given length = 7m 80cm = 7 X 100cm + 80cm = 780cm since 1m = 100cm given breadth = 5m 20cm = 5x100cm + 20cm = 520cm Length - breadth = 780-520 = 260 cm. so the room's length is longer than it's breadth by 260cm or 2m 80cm

Answer: 260cm

Step-by-step explanation:

FIRST convert the length and BREADTH into same units.

given length = 7m 80cm = 7 X 100cm + 80cm = 780cm

since 1m = 100cm

given breadth = 5m 20cm = 5x100cm + 20cm = 520cm

Length - breadth = 780-520 = 260 cm.

so the room's length is longer than it's breadth by 260cm or 2m 80cm
