Do elimination make sure that the answer you eliminate doesn't make sence A and B doesn't make since so it's C or D. so D doesn't make sense do its C.

the conference room of a hotel measures 40 ft by 50 ft has a 12-foot ceiling what is the area of the walls

Softa [21]

Answer:

The area of the walls is $2,160\ ft^{2}$

Step-by-step explanation:

we know that

The area of the walls is equal to the perimeter of the conference room multiplied by the height of the ceiling

$A=2[40+50](12)=2,160\ ft^{2}$

△FSB∼△ZDR .

Leya [2.2K]

Answer: 22 units.

Step-by-step explanation:

Here FSB and ZDR are two triangles.

In which, FS = 38 unit, FB = 55 unit, ZD = 15.2 unit and ZR = x unit.

Also, $\triangle FSB\sim \triangle ZDR$

Thus, By the property of similarity,

$\frac{FS}{ZD} = \frac{FB}{ZR}$

⇒ $\frac{38}{15.2} = \frac{55}{x}$

⇒ $x = \frac{55\times 15.2}{38}$

⇒ $x = \frac{836}{38}$

⇒ $x = 22$

Thus, ZR = 22 unit.

Please help me with this geometry question

mixer [17]

Answer:

$180+18\sqrt{3}\ in^2.$

Step-by-step explanation:

The surface area of right triangular prism is the sum of area of two base triangles and 3 area of side rectangles.

The area of base triangle is

$A_{base}=\dfrac{a^2\sqrt{3}}{4},$

where a is the length of the side of equilateral triangle. In your case, a=6 inches. Thus,

$A_{base}=\dfrac{6^2\cdot\sqrt{3}}{4}=9\sqrt{3}\ in^2.$

The area of side rectangle is

$A_{side}=ah,$

where h is the height of the rectangle. In your case, h=10 inches. Thus,

$A_{side}=6\cdot 10=60\ in^2.$

Hence, the surface area is

$SA=2\cdot 9\sqrt{3}+3\cdot 60=180+18\sqrt{3}\ in^2.$
