it should be 5 not 10 because if we consider 10m as width then the shape of the garden will become a square

height of equilateral triangle is 5rt3

diagonals of pqrs is (5rt3 X 2)-10 each

area is 1/2 X product of diagonals which entails option 2

option (3) 27

In such cases draw the diagram and then split it into right angle triangles and rectangles
