Question

The length and breadth of a Rectangular field are in the ratio 5:4.if its Perimeter is 180m.find the dimensions of the field

Answer 1

Answer:

Let the sides of the rectangle be =5x,4x

Step-by-step explanation:

ATQ

5x+4x=180

9x=180

x=20

The dimensions are 100m and 80m.

Answer 2

Answer:

• Length of the rectangle = 50 m

• Breadth of the rectangle = 40 m.

Given :

• The length and breadth of a Rectangular field are in the ratio 5:4.

• Its Perimeter = 180m.

To find :

• The dimensions of the field =?

Step-by-step explanation:

Let, The length and breadth of a Rectangular field are in the ratio be 5x and 4x.

We know that,

Perimeter of the rectangle = 2( l + b)

Substituting the values in the above formula, we get,

180 = 2 (5x + 4x)

180 = 2 × 9x

Or 9x × 2 = 180

18x = 180

x = 180/18

x = 10

Hence,

Length of the rectangle = 5x → 5 × 10 = 50 m

Breadth of the rectangle = 4x → 4 × 10 = 40 m.
