A field is in the form of right angled triangle with side 90m and 120m respectively containing the right angle.

so, area of triangle = 1/2 × height × base

hence, area of field = 1/2 × 120m × 90 m [ see figure to understand]

= 60 × 90 m²

= 540 m²

A/C to question,
leveling the field at the rate 12 Rs/m²
so, cost of the leveling of the whole field = area of field × rate
= 540 × 12
= 6480 Rs.

hence, answer is 6480
