Question

area of square is 360 cm to which is equal to 90% of the area of square with side is each of square

Answer 1

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
