Question

1. Find the perimeter of rectangles with the given dimensions.
a. Length = 12 cm. Breadth = 4 cm
b. Length = 1.5 m, Breadth=0.6 m
c. Length = 100 mm, Breadth = 35 mm
d. Length = 13 km, Breadth = 8 km
e Length = 11 m, Breadth = 70 cm​

Answer 1

Answer:

lenth 12 cm

breadth 4 cm

perimeter of rectangle is 2 ( l + b )

so, 2 ( 12 + 4 )

=16 * 2

= 32 is perimeter of rectangle

And you can do B, S, D, E yourself.

Step-by-step explanation:

a) perimeter formula = 2(l+b)

Applying it = 2(12+4)

= 2x16

= 32cm
