Question

Draw a rectangle of the perimeter 15 centimetres and sides in the ratio 3:4

Answer 1

Step-by-step explanation:

let the length of rectangle be 4x

let the breadth of rectangle be 3x

Perimeter of rectangle= 15 cm

Formula of,

Perimeter of rectangle =2(l+b)

15= 2(4x+3x)

15= 8x+6x

15= 14x

x= 15/14

x= 1.07

length of rectangle= 4x=(4×1.07)

= 4.28 cm

breadth of rectangle=3x=(3×1.07)

=3.21cm
