130 cm
Length ?
Breadth 1 m
​

Answer 1

Perimeter of the rectangle =2(l+b) 130 =2 x(l+1.)

130/2 = (l+1) .

65. =l+1

65-1. =l

l=64cm

hope it helps ☺️

Answer 2

given perimeter=130cm

lenght=?

breadth=1m. =(100cm)

changing metre into cm

1 m 1*100cm=100cm

perimeter = 2( l+b)

130. =2 ( l + 100) cm

130==200+l

l==200-130

l=70 cm
