उत्तर

It is given that,

Length of the diagonal, d = 24 m

The lengths of the perpendiculars, h1 and h2, from the opposite vertices to the diagonal are h1 = 8 m and h2 = 13 m

Area of the quadrilateral = `1/2` d(h1 + h2)

= `1/2` (24m) × (13m + 8cm)

= `1/2` (24 m) (21 m)

= 252 m2

Thus, the area of the field is 252 m2
