Question

The length of a rectangle is three times its width. Its area is 1083 cm^2. What is the perimeter of the rectangle?

Answer 1

Step-by-step explanation: Let the width be x cm

Therefore length = 3x

Area = 1083cm^2

According to the question

3x×x=1083

x^2=1083/3

x^2=361

x=19cm

Now, length= 19x3=57cm

Width = 19

Perimeter of rectangle = 2(l+b)=2(19+57)

2(76) = 152cm. ans
