Step-by-step explanation:

A)common⇒h=height,c/l.sa=curved/lateral surface area

1)volume=base area*h

1)CSA=perimeter of base*h

3)TSA=CSA+2(base area)

⇵

B)d=diagonal,h=height

1)area of parallelogram=1/2*d(h1+h2)

2)║      ║  rhombus=1/2*d1*d2

3)║      ║  trapezium=1/2*h(a+b)

C)g=gain,l=loss,sp=selling price,cp=cost price

1)g%=g/cp*100

2)l%=l/cp*100

3)sp(g)=cp(100+g%/100)

4)cp(g)=sp(100/100+g%)
