Answer:
<h2><em><u>320</u></em><em><u>0</u></em><em><u> </u></em><em><u>cm</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Length of the rectangle = 12 meters = 1200 cm
Width of the rectangle = 400 cm
<em><u>Therefore</u></em><em><u>, </u></em>
Perimeter of the rectangle = 2(l+w)
= 2(1200+400) cm
= 2 × 1600 cm
= <em><u>320</u></em><em><u>0</u></em><em><u> </u></em><em><u>cm</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

The height (h) of the rectangular prism is: 1.9 feet.
<h3>How to Find the Volume of a Rectangular Prism?</h3>
A rectangular prism has a length (l), height (h), and a width (w). The volume of the rectangular prism is calculated using the formula given as: V = (length)(width)(height).
Given the following parameters:
Volume of the rectangular prism = 30.45 ft^3,
Length (l) = 6.3 ft,
Width (w) = 2.5 ft.
Height of the rectangular prism (h) = ?
Plug in the values
(6.3)(2.5)(h) = 30.45
15.75h = 30.45
15.75h/15.75 = 30.45/15.75
h ≈ 1.9 ft

<span>To be both complex and imaginary, the answer would have to include "i" as well as have the form "a + bi". The first example, 3i - 5, fits. This would look to be the only example that does fit. The negative square root of 14 would be imaginary, but not complex.</span>
