Question

three side of triangle field are of len 15m,20m,25m find the cost of sowing seed in field at rate of 50 per m²​

Answer 1

Answer:

Rs 750

Step-by-step explanation:

Since,AC2=AB2+BC2AC2=AB2+BC2

=> (25)2=(15)2+(20)2(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×BC12×AB×BC

= 12×15×2012×15×20

=150m2150m2

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

Cost of sowing seed for

150m2=150×5150m2=150×5

= RS. 750
