a
The area of a square and a rectangle are
equal. If the side of the square is 30 cm and
the length of the rectangle is 50 cm, then
find the perimeter of the rectangle.​

Answer 1

Answer:

68 cm

Step-by-step explanation:

area of square = 30 * 30

= 900

let the one side of rectangle be x and other side is given as 50

so area of rectangle is L*B = 50*x

= 50x

according to the question

area of square = area of rectangle

900 = 50x

x = 18

so perimeter would be 50+18 = 68 cm

Answer 2

30×30=900

let breadth of a rectangle = x

50×x=50x

ATQ

50x =900

x=900/50

x=18

2(l+b)

2(50+18)

100+36
