Answer:
=225/16cm^2
Step-by-step explanation:
Given
The ratio of the length to the width of the rectangle =3:2.
The perimeter of a rectangle = 60cm.
Solution
Let length=3x
width=2x
Perimeter of rectangle=2(length + width)
2(3x+2x)=60
5x*2=60
10X=60
X=60/10
X=6
SO LENGTH =3×6=18cm
WIDTH=2×6
=12cm
Let perimeter of the square=5x
Length of rectangle=6x
6x = 18
X=18/6
X=3
SO PERIMETER OF SQUARE=5×3
4SIDE=15
Side=15/4
Area of square=15/4×15/4
=225/16cm^2
