Question

How do you draw and lable a perimeter using rectangles. The length is x feet the width is( x-7) and write 3 different expressions that you could use to find the perimeter? ????

Answer 1

P=L+L+W+W
P=2L+2W
P=2(L+W)
those are 2 ways so


first one
P=x+x+(x-7)+(x-7)

2nd way
P=2x+2(x-7)

3rd way
P=2(x+x-7)
