3. Area of triangle
4. Area of circle,
5. Simple Interest,​

Answer 1

1. area of parallelogram=base ×prependicular height

2. profit percent=profit×100/cost price

3. area of triangle =½×base ×height

4. area of circle =πr² ( π=22/7)

5. simple interest=principal×rate×time/100

Answer 2

Step-by-step explanation:

1) Area of parallelogram= base×height

2) Profit percent= S.P- C.P

3)Area of triangle =1 ×base×height

2

4)Area of circle= πr²

5)Simple Interest= A = P(1 + rt)
