Question

The parameter of a rectangular field and a square field are same if one side of rectangular field is 9 and one side of a square field is 7 and find the area of a rectangular field and the total area of both the fields.​​

Answer 1

Answer:

The answer is :-

$45 {cm}^{2}$

Step-by-step explanation:

As given, perimeter of square and rectangle are equal so if we find the perimeter of square we will get the perimeter of rectangle.

Perimeter of square = 4 × Side

= 4 × 7

= 28cm

Lets take breadth as b

Perimeter of rectangle = 2 × (l + b)

28 = 2 × ( 9 + b)

28 = 18 + 2b

28 - 18 = 2b

2b = 10

b = 10 ÷ 2

b = 5

Area of rectangle = l × b

= 9 × 5

$answer \: = \: 45 {cm}^{2}$
