Question

the side of a rectangle are in the ratio 2:3and the perimeter is 20 cm find the side of rectangle​

Answer 1

Answer:

let the common ratio is x

so length is 2x cm and breadth is 3x cm

2(2x+3x)=20

2.5x=20

10x=20

x=20/10=2

so length is 2.2cm=4cm

breadth is 3.2 cm =6 cm

Answer 2

Given:

• Ratio of the sides of a rectangle is 2 : 3.
• Perimeter of the rectangle is 20cm.

To find:

• Side of the rectangle?

⠀⠀⠀⠀⠀⠀⠀

Solution:

Let the three sides of the triangle be 2x and 3x.

As we know that,

⋆ Perimeter of rectangle = 2(Length + Breadth)

Here,

• Perimeter = 20 cm
• Length = 2x
• Breadth = 3x

Putting the values,

➜2(2x+ 3x) = 20

➜2 × 5x = 20

➜10x = 20

➜x = 20/2

➜x = 2cm

Therefore,

• Length of the rectangle = 2x = 2 × 2= 4cm
• Breadth of the rectangle = 3x = 3 × 2 = 6cm
