In the figure below, the two triangular faces of the prism are fight triangles with sides of length 3, 4, and 5. The other three

olasank [31]

The figure of the prism is attached below.

The total surface area of the prism equals the sum of areas of two triangles and the three rectangles.

Surface Area of Prism = Area of 2 Triangles + Area of 3 Rectangles.

Area of a Triangle = 0.5 x Base x Height
Area of a Triangle = 0.5 x 3 x 4 = 6 square units

There are 3 rectangles. From the figure we can see that the bottom most rectangle has the dimensions 4 by 6. The left most rectangle has the dimensions 3 x 6 and the right most rectangle has the dimensions 5 by 6.

So, the Area of 3 rectangles will be = (4 x 6) + (3 x 6) + (5 x 6) = 72 square units

The Surface Area of the prism will be:

Surface Area = 2 (4) + 72 = 84 square units

Thus the correct answer is option A

kevin has a rectangular-shaped garden its 15 feet by 12 feet wide he plants 36 square feet of tomatoes what percent of the garde

dusya [7]

Answer:

<u>20%</u> of the garden are tomatoes planted.

Step-by-step explanation:

Given:

Kevin has a rectangular-shaped garden its 15 feet by 12 feet wide.

He plants 36 square feet of tomatoes.

Now, to find the percent of the garden where tomatoes planted.

We need to get the total area of the garden first:

Total area of the garden = $15 feet by 12 feet.$

= $15 feet\times 12 feet.$

= $180\ square\ feet.$

So, getting the area of the garden 180 square feet.

Now, we calculate the percent of the area of garden where tomatoes are planted:

$\frac{Area\ of\ tomatoes\ planted}{Total\ area\ of\ garden} \times 100.$

$=\frac{36\ square\ feet}{180\ square\ feet} \times 100$

$=\frac{36}{180} \times 100$

$=\frac{3600}{180}$

$=20\%.$

Therefore, 20% of the garden where are tomatoes planted.

Find the approximate side length of a square game board with an area of 171 in?

Makovka662 [10]

<em>Greetings from Brasil...</em>

According to the statement of the question, we conclude that the area of a square is requested, whose value is 171 in²

The area of a square is given by the expression:

A = S²

<em>where S is the side of the square - just what we want to know</em>

So:

A = S²

171 = S²

√171 = S

<h3>S ≈ 13.08in</h3>
