Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Length = 11 1/3 ft; Width = 4 2/3 ft

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.
