Explanation

Given the area of the square garden is 529 m²:

Step 1: Find the length of one side of the square.

Area = side²

529 = side²

side = √529

side = 23 m

Step 2: Calculate the perimeter of the square.

Perimeter = 4 × side

= 4 × 23

= 92 m

The length of wire required to cover all its sides is equal to the perimeter.

Explanation

Given:

Selling Price (SP) = Rs. 49755

Profit Percentage = 7%

Let Cost Price (CP) be x.

SP = CP + Profit

49755 = x + 7% of x

49755 = x + 0.07x

49755 = 1.07x

x = 49755/1.07

x = 46500

To determine significant figures in 10.03:

• All non-zero digits are significant → 1 and 3
• Zeros between non-zero digits are significant → 0 between 1 and 3
