Question

the perimeter of a rectangle is 140cm. if the width is 3/4 of the length find the dimensions of the rectangle?
​

Answer 1

Step-by-step explanation:

Given: Perimeter of Rectangle =140cm

Ratio of sides =3:4, so let length=4x, breadth=3x

Perimeter of Rectangle =2(l+b)

∴2(4x+3x)=140

7x=70

x=10

∴length=40, breadth=30

∴ sides of rectangle =30cm,40cm

Diagonal of Rectangle =

l
