Question

6. The length of a rectangle is three times its width and the length of its diagonal is 6/10 cm,The perimeter of the rectangle is.
​

Answer 1

Answer:

48 cm

Step-by-step explanation:

Let the width of the rectangle be x

an length of the rectangle will be 3x

Given,

length of its diagonal is 6√10 cm

so by Pythagoras theorem

x^2 +(3x)^2 =(6√10)^2

x^2+9x^2= 360

10x^2=360

x^2=36

x=6

So breadth of the rectangle = 6cm

length of the rectangle= 3×6cm=18cm

So,

Perimeter of the rectangle = 2(6+18)cm

= 2×24cm=48cm

Hence perimeter of rectangle is 48 cm
