a rectangle has base length L and width W. if the length is increased by 2 and the width is decreased by 4, a new rectangle is formed.
a. write an expression for the length of the new rectangle in terms oof L.
b. write an expression for the width of the new rectangle in terms of W.
c. find the perimeter and the area of the new rectangle if L= 8 and W = 6
a)L+2
b)W-4
c)Length of new rectangular = 8+2=10
Width of new rectangular = 6-4=2
perimeter = 2L+2W
10(2)+2(2)=24
area = LW
area = 10(2)= 20
