Question

the perimeter of a rectangular sheet is 100 cm. of length is 35cm. find its breadth.​

Answer 1

Answer: The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, its breadth will be 15 cm.

Perimeter of a rectangular sheet = 2 (Length + Breadth)

100 = 2l + 2b

100 = 2 × 35 + 2b

100 = 70 + 2b

2b =100 - 70

b = 30/2

b = 15 cm

Answer 2

Answer:

PERIMETER OF RECTANGLE = 2(L+B)

=100cm

LENGTH = 35cm

NOW , LET BREADTH = x

2(x+35)=100

2x+70=100

2x= 30

x=30/2

x= 15

HENCE , BREADTH = 15cm
