Part (a)
<h3>Answer:
2(2.4+w) = 14.2</h3>
--------------
Explanation:
L = 2.4 = length
W = unknown width
The perimeter of any rectangle is P = 2(L+W)
We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2
========================================================
Part (b)
<h3>Answer:
w = 4.7</h3>
--------------
Explanation:
We'll solve the equation we set up in part (a)
2(2.4+w) = 14.2
2(2.4)+2(w) = 14.2
4.8+2w = 14.2
2w = 14.2-4.8
2w = 9.4
w = 9.4/2
w = 4.7
The width must be 4.7 cm.

Arc length of the quarter circle is 1.57 units.
Solution:
Radius of the quarter circle = 1
Center angle (θ) = 90°
To find the arc length of the quarter circle:
![$=2 \times 3.14 \times 1\left(\frac{90^\circ}{360^\circ}\right)](https://tex.z-dn.net/?f=%24%3D2%20%5Ctimes%203.14%20%20%5Ctimes%201%5Cleft%28%5Cfrac%7B90%5E%5Ccirc%7D%7B360%5E%5Ccirc%7D%5Cright%29)
![$=2 \times 3.14 \times 1\left(\frac{1}{4}\right)](https://tex.z-dn.net/?f=%24%3D2%20%5Ctimes%203.14%20%20%5Ctimes%201%5Cleft%28%5Cfrac%7B1%7D%7B4%7D%5Cright%29)
Arc length = 1.57 units
Arc length of the quarter circle is 1.57 units.
None of these answer choices are correct. The answer would be 51. 52+53=105
105-54=51
