Question

please solve this step By step ​

Answer 1

Answer:

area of triangle =1/2 * b*l

150= 1/2 *15*l

150*2=15l

300/15= l

l=20

H2= l2+ b2

H2= (20)2 +(15)2

H2 = 400+225

H2=625

H=√625

H=25

perimeter = 20+15+25= 60

given, cost of 15m= 225

then 15*4=60m =225*4

60m =900rs

so, option (d) is the right answer
