Question

The area of a rectangle is 360 cm2 , which is equally to 90% of the area of a square . What is each side of the square ?

Answer 1

area of rectangle= 360cm2
area of square=x
90/100*x=360
x=400=area of square
side=root 400=        20cm

Answer 2

Answer:

Step-by-step explanation:

Let the area of the square be x

Area of rectangle = 360 m square

So,

90x/100  = 360 m square

x = (360 x 100/90) m square

x = 400 m square

Side of square = √400m square

                        = 20 m
