1.	The area of the parallelogram-presented by vectors R-21 457 andBolto
Answer» LET A=2i+3j and B=i+4j .AREA of paralleogram A∗B=(2i+3j+0k)∗(i+4j+0k)For i component we have,(3∗0)−(4∗0)=0For j component we have,(0∗2)−(1∗0)=0For k component we have,(2∗4)−(1∗3)=5.Now take the magnitude of this vector to find the area of the parallelogram:A∗B= 0 2 +0 2 +5 2 =0+0+5=5unitsExplanation:
