Question

find the breadth of rectangle if the length is 12 cm and perimeter is 40 cm​

Answer 1

Answer:

8cm

Step-by-step explanation:

Perimeter of a rectangle(P)=2(length + breadth)

Given P=40 cm and length(l) = 12 cm

2(l+b)=40 cm

2(12+b)=40

24+2b=40

2b=40–24

2b=16

b=8 cm

Hence breadth(b) of a rectangle is 8 cm

Answer 2

Step-by-step explanation:

Perimeter of a rectangle(P)=2(length + breadth)

Given P=40 cm and length(l) = 12 cm

2(l+b)=40 cm

2(12+b)=40

24+2b=40

2b=40–24

2b=16

b=8 cm

Hence breadth(b) of a rectangle is 8 cm
