Question

The area of a square filed is 8 hectares. How long would a man take to cross it diagonally by walking at the rate of 4 km per hour?

Answer 1

Given, area of square field = 8 hectares

= 8 x 0.01[1hectare = 0.01 km²]

= 0.08 km²

Now, area of square field = (side of square)² = 0.08

Distance covered by man along the diagonal of square field = length of diagonal
