Question

The length of a rectangle is three times its width. It the perimeter of the rectangle is 96m.Find the length and breadth of the rectangle.​

Answer 1

Answer:width = 12 cm

length = 12*3= 36cm

Step-by-step explanation:

let the width be x

then length = 3x

perimeter = 96 cm

since, perimeter = 2(l+b)

2(3x+x)=96cm

6x+2x=96cm

8x=96cm

x=96/8= 12

ANS - width = 12 cm

length = 12*3= 36 cm

Answer 2

Answer :-

Let width be x

Length = 3x

According to the question :-

Perimeter = 2 ( l + b ) = 96

2 ( x + 3x ) = 96

2 ( 4x ) = 96

8x = 96

x = 96/8

x = 12

Length = 12 cm

Length = 12 cm Width = 12 × 3 = 36 cm

Additional information :-

Area of rectangle = Length × Breadth

Perimeter of square = 4 × side

Area of square = side × side =
