Question

A rectangle (length=5 cm) and square (tide = 10 cm) have equal area What is the perimeter of the rectangle?​

Answer 1

Answer:

Side of the square = 10 cm

Therefore, area of the square = s×s

= 10cm×10cm

= 100 cm

Breadth of the rectangle = 5cm

Length of the rectangle = 100÷5

= 20 cm = Length

Therefore, perimeter of the rectangle = 2×(l+b)

= 2×(20+5)

= 2×25cm

= 50cm(Ans)

Answer- 50cm is the perimeter of the rectangle.

Answer 2

Answer:

we know that area of rectangle and square is equal .

Then ,

Let breadth of rectangle = x

Now,

Side ^2=5×x

100= 5×x

x= 100÷5

x=20

NOW, AS PER QUESTION ,

PERIMETER OF RECTANGLE = 2(l+b)

2(5+20)

2× 25

50 cm = ANS
