1.	13.Find the area of a parallelogram in a polynomial expression from the given figaAB = (x+3), DE =(x-4)-(x+3)
Answer» area of parallelogram = b×h = AB×DE = (x+3)(x-4) = (x^2-x-12 ) sq unit base of parallelogram,AB=x+3height of parallelogram,DE=x-4therefore area of parallelogram=ABxDE=(x+3)(x-4)=x²-4x+3x-12=x²-x-12

13.Find the area of a parallelogram in a polynomial expression from the given figaAB = (x+3), DE =(x-4)-(x+3)

Answer»

area of parallelogram = b×h = AB×DE = (x+3)(x-4) = (x^2-x-12 ) sq unit

base of parallelogram,AB=x+3height of parallelogram,DE=x-4therefore area of parallelogram=ABxDE=(x+3)(x-4)=x²-4x+3x-12=x²-x-12
