Step-by-step explanation:
As we know area of triangle= 1/2* Base * Altitude
So, 1/2* (2a-b)*(1/2b+3)
= 1/2*2a -1/2*b= a-b/2= 2a/2-b/2= 2a-b/2
Now, 2a-b/2 * (1/2b+3)
(2a-b/2 * b/2) + (2a-b*3/2)
= (2a-b sq./4) + (2a-3b/2)
= (2a-b sq./4) + (2(2a-3b)/2)
=(2a-b sq./4) +(4a-6b/2)
=2a +4a-b sq. -6b/4
=6a-b sq. - 6b/4
=a-b - b sq. /4
