simplified expression of the area of this rectangle.

Question

The length of a rectangle is given by x + 2 and its width is equal to 3. Give a simplified expression of the area of this rectangle.

Answer 1

Length(l)  =  x + 2

Breadth (b)  =  3

Area of the Rectangle (A)  =  l X b

Substitute l = (x + 2) and b = 3 in above equation of area

Area  =  (x + 2) X 3

          =  3(x) + 3(2)

          =  3x + 6

Answer :

Area  of the Rectangle  =  3x + 6
