Question

Would a square or a circle contain more area if they have enough brick to make a 10-kilometer fence/wall? Please show your calculations.

Answer 1

Length of wall = 10km

side of square= 10km

area of square= 10²= 100km²

radius of circle = 10/2 = 5km

area of circle = 3.14 × 5²

area of circle = 3.14 × 25

area of circla = 78.5 km²

area of square >>> area of circle
