Answer :

• The ratio of length is to the area of the Rectangular field is 1:15.

Step-by-step explanation:

To Find :

The ratio of length is to area of the Rectangular field

Solution:

Given the,

• Area of the rectangular field =

450m²

• Breadth of the field = 15m

.. The length of the filed:

As we know that,

Perimeter of rectangle = 2 ( Length +

Breadth),

=> 2 (Length + 15 ) = 450

=> Length + 15 = 450/2

=> Length + 15 = 225

=> Length = 225 - 15

=> Length = 210

Hence, the length of the Rectangular field

is 210m.

Now, Area of the Rectangular field:

As we know that,

Area of rectangle = Length x Breadth,

=> Area = 210m x 15m

=> Area = (210 x 15 )m²

=> Area = 3150m²

Hence, the area of the field is 3150m².

Now, According the question,

The ratio of length is to the area of the Rectangular field.

=> Length: Area

=> 210: 3150

=> 42: 630

=> 14: 210

=> 7: 105

=> 1:15

.. The ratio of length is to the area of the Rectangular field is 1:15.
