Answer:
The answer is :-
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
