Question

three side of a triangular field are of length 15 metre 20 metre and 25 metre respectively find the cost of showing seed in the field at the rate of ₹50 per square ​

Answer 1

Answer:

Since,AC2=AB2+BC2

=> (25)2=(15)2+(20)2

=> 625=225+400

=> 625 = 625

So, the triangular field is right angled at B

Area of the field = 12×AB×BC

= 12×15×20

=150m2

So, the cost of sowing seed is RS. 5 per sq m

Cost of sowing seed for

150m2=150×5

= RS. 750
