cm and its breadth is 8 cm, what is
the length of the rectangle ? *​

Answer 1

Answer:

given that perimeter of rectangle =42 let breadth be x length =2x perimeter of rectangle = 2 (l+b) 42=2 (2x+x) 42 =4x+2x

Answer 2

Answer:

length = ?

breadth = 8 cm

perimeter = 42 cm

Area of rectangle 2 (l+b)

42 = 2 ( l + 8 )

42/2 = 8 + l

21 -8= l

l = 13cm

length = 13 cm

breadth = 8 cm
