Given the formula for the perimeter of a rectangle where l represents the length and w represents the width. 2(l + w) what does the 2 represent in this formula? a) the 2 represents the perimeter. b) the 2 represents the two width pairs. c) the 2 represents the two length pairs. d) the 2 represents the two sets of length and width pairs.

The 2

A rectagle has 4 sides. There are 2 lengths and 2 widths.

The would be written like this to start with

P = L + L + W + W

P = 2L + 2W             Using the distributive property 2 can be taken outside the brackets

P = (2L + 2W)

P = 2(L + W)              You have shown how the 4 sides can be written more efficiently.

The answer is D <<< Answer

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
