The length of a rectangular area is 30 m and width is 20 m. Find its perimeter.
a)100 m
b)80 m
c)50 m
d)90 m​

Answer 1

Answer:

Length = 30m

Breadth = 20m

Perimeter = 2(Length + Breadth)

= 2 ( 30 + 20 )

= 2 x 50

= 100 m

Answer 2

Answer:

perimeter=2 (l+b)

2 (30+20)m

2×50m

100 m is the answer.
