Question

the sides of rectangle are in the ratio 2:3:4 and its perimeter is 63 cm.What are lenghts of its sides?​

Answer 1

$\huge \bold \purple{solution}$

Let the length of the rectangle be 2x.

Let the breadth of the rectangle be 3x.

Perimeter of rectangle = 63cm

Perimeter of rectangle = 2(L+B)

= 2(2x+3x) = 63

= 4x + 6x = 63

= 10x = 63

= x= 63/10

= x= 6.3

Breadth = 3×6.3 = 18.9

Length = 2×6.3 = 12.6

Hence, the length of the rectangle is 12.6.
