Answer:
20 cm
Step-by-step explanation:
Let the side of the square is x
∴ Area = x² (∵ Area of Square = Side²)
Given that
90% Area of Second Square = Area of First Square
∴ 90% of x² = 360
(90/100)x² = 360
x² = (360 × 100) ÷ 90
x² = 400
x² = 20²
∴ x = 20 (∵ √400 = 20)
Hence, side of second square is 20 cm
