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

Answer:
simple way and Quick way
Step-by-step explanation:
A=1/2*b*h
A=1/2*120*90
A=60*90
A=540m²
Hence,Levelling the cost of whole field
=>540×12
=>₹6480
