Question

6. The areas of a square and rectangle are equal. If
the side of the square is 20 cm and the breadth of the
ectangle 10 cm, find the length of the rectangle and
s perimeter.​

Answer 1

Answer:

area of square =area of rectangle

(20)²= l(10)

400=10l

length of rectangle =40cm

perimeter of rectangle =2(l+b)

=2(40+10)

=2(50)

perimeter of rectangle=100cm

Answer 2

Answer:

Given that the area of a square and rectangle are equal.i.e,S×S = lb.

And also given that the side of a square is 20cm,breadth of the rectangle is 10cm.

Explanation:

20×20 = l×10

400 = 10l

400/10 = l

Zeroes in the numerator and denominator gets cancelled.

And the length of the rectangle would be 40cm.

Perimeter of the rectangle is:

2(l+b)

2(40+10)

2(50)

100cm is the perimeter of the rectangle.
