Question

the sides of a triangular field are 51 m, 37 m and 20 m. Find the number of flower beds that can be prepared, if each bed
is to occupy 9 m2, of space.​

Answer 1

find an angle using the cos rule first (cos C = (a2 + b2 - c2) / (2*a*b) )

then find the area of the triangle using that angle (1//2 * 2 sides *sin of included angle) (1/2 * a * b) * (sin theta)

divide the area of the triangle with that of a flower bed and you will get the answer
