The surface area of the tent is 21.4 m²

Step-by-step explanation:

To find the surface area of a prism you must calculate:

1. The perimeter of the base

2. The area of the base

3. The height of the prism

We have a triangular prism:

Its base is an equilateral triangle of side length 2 m and height 1.7 m

The height of the prism is 3 m

∵ The surface are of the prism is:

   S.A = perimeter of the base × height + 2 × area of the base

∵ The perimeter of the equilateral triangle = 3 × length of a side

∵ The length of the side = 2 m

∴ The perimeter of the base = 3 × 2 = 6 m

∵ The area of the triangle = \frac{1}{2} × base × height

∵ The length of the base of the triangle = 2 m

∵ The height of the triangle = 1.7 m

∴ The area of the base = \frac{1}{2} × 2 × 1.7 = 1.7 m²

∵ S.A = perimeter of the base × height + 2 × area of the base

∵ The perimeter of the base = 6 m

∵ The area of the base = 1.7 m²

∵ The height of the prism = 3 m

∴ S.A = 6 × 3 + 2 × 1.7

∴ S.A = 18 + 3.4

∴ S.A = 21.4 m²

The surface area of the tent is 21.4 m²

We have been given that Cam's tent is a triangular prism. We are asked to find the surface area of Cam's tent including the floor.

The total surface area of tent would be sum of area of all sides.

We can see that two sides of tent are triangular, so their area will be equal to area of triangle.

\text{Area of 2 triangular sides}=2\times\frac{1}{2} \times \text{Base}\times \text{Height}

\text{Area of 2 triangular sides}=2\times\frac{1}{2} \times \text{2 m}\times \text{1.7 cm}

\text{Area of 2 triangular sides}=3.4 \text{ m}^2

Now we can see that tent has two rectangular sides.

\text{Area of 2 rectangular sides}=2\times \text{Length}\times \text{Width}

\text{Area of 2 rectangular sides}=2\times \text{2 m}\times \text{3 m}

\text{Area of 2 rectangular sides}=12\text{ m}^2

We can see that floor of tent is also rectangular.

\text{Area of floor}=3\text{ m}\times 2\text{ m}

\text{Area of floor}=6\text{ m}^2

\text{Tent's total area}=3.4\text{ m}^2+12\text{ m}^2+6\text{ m}^2

\text{Tent's total area}=21.4\text{ m}^2

Therefore, the total area of tent is 21.4 square meters.

The figure below shows rectangle ABCD.
kipiarov [429]

Answer: We can find out the missing statement with help of below explanation.

Step-by-step explanation:

We have a rectangle ABCD with diagonals AC and BD ( shown in given figure.)

We have to prove: Diagonals AC and BD bisect each other.

In triangles, AED and BEC.

\angle ADB \cong \angle CBD ( By alternative angle theorem)

AD\cong BC ( Because ABCD is a rectangle)

\angle CAD\cong \angle ACB  ( By alternative angle theorem)

By ASA postulate,\triangle AED\cong \triangle BEC

By CPCTC, BE\cong ED and CE\cong EA

⇒ BE= ED and CE=EA

By the definition of bisector, AC and BD bisect each other.

MrRa [10]

Answer:

50+50x

Step-by-step explanation:

they're asking you to use distributive property

so what you have to do is multiply everything that is in the parenthesis by 10

5x10=50

5x10x=50x

so the answer is 50+50x

have a great day :D
