If a represents a vector two units in length directed due west, b represents a vector three units in length directed due north and a+b=c-d and 2b-a=c+d.
find the magnitudes and directions ofc and d.

Step-by-step explanation:

Given

Vector A has two units in length due to west i.e.

Vector B has one unit in length due to North i.e.

Also

i.e.

also

i.e.

From 1 and 2

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
