Answer:

C. 469 in²

Step-by-step explanation:

The net of the object is a rectangle that is 28 inches long and 14 inches wide. Its area is 392 square inches.

In addition, there are two triangles with base 11 inches and height 7 inches. Together, they have the area of a rectangle 7 by 11, or 77 square inches.

The total surface area of the prism is then ...

(392 + 77) in² = 469 in²

_____

The area of a rectangle is the product of its length and width.

The area of a triangle is half the product of its base and height. So, the area of two identical triangles is the product of their base and height.

_____

<em>Comment on the geometry</em>

This geometry cannot exist as shown. The height of the triangular face is closer to 6.454 inches than to 7 inches.

Calculate the area of triangle ABC with altitude, CD, given

defon

Answer:

37.5 square units

Step-by-step explanation:

Given:

A(-6,-4), B(6,5), C(-1,6), and D(2, 2), where CD is the altitude if ∆ABC

Required:

Area of ∆ABC

SOLUTION:

Area of a ∆ABC =½*AB*CD

✍️ $AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{6 -(-6))^2 + (5 -(-4))^2$

$AB = \sqrt{12^2 + 9^2}$

$AB = \sqrt{144 + 81}$

$AB = \sqrt{225} = 15$

✍️ $CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{2 -(-1))^2 + (2 - 6)^2$

$CD = \sqrt{(3)^2 + (-4)^2}$

$CD = \sqrt{9 + 16}$

$CD = \sqrt{25} = 5$

✍️Area of a ∆ABC =½*AB*CD

= ½*15*5

✅ Area = 37.5 square units

What is the volume of the figure below?

WITCHER [35]

Answer: 270 cubic centimeters

Step-by-step explanation:

bh/3 is the formula so...

because it's a right triangle we multiply the legs together:

9*12 = 108

and we divide by 2

108/2 = 54

height is 15

(15*54)/3 = 810/3 = 270

Our answer is 270 cubic centimeters.
