Question

9. The perimeter of a rectangle is 32cm and its length is 10cm. Find Its breadth​

Answer 1

Length = 10 cm. b= 6. So, Breadth = 6 cm.

Answer 2

the breadth of rectangle is 6cm.

given :-

length of rectangle = 10 cm

perimeter of rectangle = 32cm

to find :-

breadth of rectangle

concept -

using formula of perimeter of rectangle

where as,

length = l

breadth = b

solution :-

perimeter of rectangle = 2 ( l + b)

32cm = 2 ( 10 cm + b)

32cm ÷ 2 = (10cm b)

16 cm = (10 cm + b)

16 cm - 10 cm = b

6cm = b

b = 6cm

hence , the breadth of rectangle is 6cm.

hope this helps.
