Answer:

Steve should order the round pizza to get more crust.

Step-by-step explanation:

They are essentially asking which pizza has a larger perimeter, because we can assume that the crust is of equal thickness on either pizza. To find the side length of the square pizza we find the square root of the area, \begin{document}\\\sqrt{49}\\\end{document}\\=7 and to get the perimeter from the side length we multiply by 4, \begin{document}\\7*4=28\\\end{document}. To get the perimeter of the round pizza we first find the radius from the area. The formula for area of a circle is π*r^2 so we divide the area by π to get 49, and the square root of 49 gives us a radius of 7. To get perimeter of a circle, also called circumference, you multiply the diameter times π and the diameter is twice the radius. We multiply 7 by 2 to get the diameter, 14 and then multiply by pi to get the circumference which is approximately 43.982. 43.982 is larger than 28 so Steve should order the round pizza.

Answers:

  • The lengths of sides PQ and RS are <u>   13   </u>
  • The lengths of sides QR and SP are <u>   </u><u>20  </u>

This is a 13 by 20 rectangle.

============================================================

Explanation:

Refer to the drawing below.

Let x be the length of side SP. Since we're dealing with a rectangle, the opposite side is the same length. Side QR is also x units long.

We're told that RS = SP - 7 which is the same as saying RS = x-7

We also know that PQ = x-7 as well because PQ is opposite side RS.

In short, we have these four sides in terms of x

  • PQ = x-7
  • QR = x
  • RS = x-7
  • SP = x

as shown in the drawing. The four sides add up to the perimeter of 66.

PQ+QR+RS+SP = perimeter

PQ+QR+RS+SP = 66

(x-7)+x+(x-7)+x = 66

4x-14 = 66

4x = 66+14

4x = 80

x = 80/4

x = 20

Use this x value to find the unknown side lengths.

  • PQ = x-7 = 20-7 = 13
  • QR = x = 20
  • RS = x-7 = 20-7 = 13
  • SP = x = 20

In short, this is a 13 by 20 rectangle.

-----------------

Check:

perimeter = side1+side2+side3+side4

perimeter = PQ+QR+RS+SP

perimeter = 13+20+13+20

perimeter = 33+33

perimeter = 66

The answer is confirmed.
