Answer:

480 m²

Step-by-step explanation:

<u>Surface area, 4 faces only, excluding the area of the base:</u>

A = 4*(1/2*12*20) = 480 m²

<u>Total surface area, including the base:</u>

S = 480 + 12² = 624 m²

Answer:

d

Step-by-step explanation:

The segment inside the triangle bisects the angle and divides the opposite sides into segments that are proportional to the other two sides, that is

$\frac{x}{17}$ = $\frac{37.5}{52.5-37.5}$ = $\frac{37.5}{15}$ ( cross- multiply )

15x = 637.5 ( divide both sides by 15 )

x = 42.5 → d
