Question

find the perimeter of a rectangle whose length and breadth are 2 metre 15 cm and one metre 25 CM respectively​

Answer 1

Answer:

Step-by-step explanation:l=2m15cm

1m=100cm

2m=200cm

2m15cm=215cm

B=25cm.

Perimeter=2(l+b)

=2(215+25)

=480m

→ Answer : Perimeter of rectangle = 6.8 m

→ To Find : Perimeter of a rectangle

→ Step-by-step explanation :

Perimeter of rectangle = 2 ( l + b )

Length (l) = 2 m 15 cm

Breadth (b) = 1 m 25 cm

=> Perimeter = 2 ( 2 m 15 cm + 1 m 25 cm)

=> Perimeter = 2 ( 3 m 40 cm)

=> Perimeter = 2 ( 3 m + 0.4 m) Since [ 40 cm = 40/100 m = 0.4 m]

=> Perimeter = 2 ( 3.4 m )

=> Perimeter = 6.8 m = 680 cm
