Question

The area of a square park is 25sq km . The time taken to complete a round of the filled once , at a speed of 3 km/h , is .

Please tell me right answer with Solutions​

Answer 1

Answer:

Area of square = side × side= 25 sq. km.

Side = 5 km.

perimeter = 4 × 5 = 20 km.

Time taken to complete one round with speed 3 kmph,

= 203

= 6.66 hours

= 6 hour 40 minutes

Answer 2

Answer:

since the perimeter of a square is given by P = 4s, where s is the length of the side. We can easily determine the length by isolating s from the formula above:

s = P/4 = 32 / 4 = 8 yd

 

The area of the square field = s × s

Substitute the value of s, we have:

Area = 8 × 8 = 64 yd2

The area of the square field is therefore 64 yd2.
