Answer:

<h2>823.7 m²</h2>

Step-by-step explanation:

If a figure A and a figure B are similar, then

\dfrac{area_A}{area_B}=k^2    (*)

<em>k</em><em> - similarity scale</em>

<em />

Calculate the similarity scale:

k=\dfrac{6}{5}

We have the surface area of the smaller prism 572 m².

Substitute to the formula (*):

\dfrac{x}{572}=\left(\dfrac{6}{5}\right)^2\\\\\dfrac{x}{572}=\dfrac{36}{25}\qquad\text{cross multiply}\\\\25x=(36)(572)\\\\25x=20,592\qquad\text{divide both sides by 25}\\\\x=823.68\approx823.7\ m^2

Ganezh [65]
Present value of annuity is given by PV = P(1 - (1 + r)^-n)/r
25230 = P(1 - (1 + 0.0671/12)^-36)/(0.0671/12)
P = 0.0671(25230) / 12(1 - (1 + 0.0671/12)^-36) = 775.69

Therefore, you pay 36 x 775.69 = $27,924.84 over the life time of the loan.
