Answer 1

Answer:

area of square=90m²

a²= 90m²

a =√90m²

a = 9.48m

hence one side of square is 9.48 meter..

Answer 2

Answer:

9 and 10

Step-by-step explanation:

Given,

Area of greeting card = 90 m²

(side)² = 90

          = 2 * 5 * 3²

Thus,

Side = √2 * 5 * 5²

⇒ Side = 3√2 * 5

⇒ Side = 3√10

⇒ Side = 3 * 3.2

⇒ Side = 9.6 cm

Therefore,

Length of the Side lies between 9 and 10.
