There is a square plot with side length equal to 13 m. A farmer wanted to grow grass on half of his field and plough the remaining land. Find the area of land used to grow the grass.
84.5 m2
Total area of a square = Side × Side = 13 x 13 = 169 m2
Area on which grass is grown = half of the total area = 1692 = 84.5 m2
