Question

A. The perimeter of a rectangle is twice the length plus twice the width. If L represents the length and W represents the​ width, write an algebraic expression that represents the perimeter.
b. Calculate the perimeter of a rectangle with length 1010 inches and width 1818 inches.
c. The area of a rectangle is the product of its length and width. Write an algebraic expression in L and W that represents its area.
d. Calculate the area of a rectangle with length 1010 inches and width 1818 inches.

a. The algebraic expression that represents the perimeter of the rectangle is??

Answer 1

Perimeter P = 2L + 2W

b.  P =  2*1010 + 2*1818 = 2020 + 3636 = 5656 inches

c.  Area A  = WL

d  Area  = 1010*1818 =  1836180 in^2
