Question

The length of a rectangle is 3cm more than its breadth.If the perimeter of rectangle is 46cm,find the dimensions of the rectangle​

Answer 1

Let breadth be x cm

length = x+3 cm

Perimeter = 2( l + b )

46 = 2 ( x + x +3 )

46 = 2 ( 2x + 3 )

46 = 4x + 6

46 - 6 = 4x

40 = 4x

x = 10

Breadth = x = 10 cm

Length = x+3 = 10 + 3 = 13 cm

HOPE IT WILL HELP ☺️☺️
