Example Question #272 : Plane Geometry

Set_3

Figure not drawn to scale

Find the perimeter of the trapezoid.

Possible Answers:

Correct answer:

Explanation:

In order to find the perimeter of the trapezoid, you must add up the lengths of all the sides of the trapezoid.

Because the lengths of the trapezoid are in inches, the answer is 40 in.

Example Question #2 : How To Find The Perimeter Of A Trapezoid

What would you call a polygon with four sides and four angles, all of different measurements?

Possible Answers:

Rectangle

Square

Rhombus

Quadrilateral

None of these

Correct answer:

Quadrilateral

Explanation:

A quadrilateral has four sides and four angles, but no restrictions on how the lengths or measures are related. Thus, quadrilateral is the right answer.

In squares and rectangles, all four angles measure 90 degrees; thus the angles are all of equal measurements, making square and rectangle incorrect answer choices. A rhombus has two sets of angles of equal measurements, and would also be incorrect.

Example Question #272 : Plane Geometry

Mrs. Green's garden is shaped like a trapezoid.  She wants to build a fence on the perimeter of her garden.  The sides of her garden measure . How long will the fence need to be?

Possible Answers:

Correct answer:

Explanation:

To calculate the perimeter of a trapezoid, find the sum of the four sides.  

Example Question #3 : How To Find The Perimeter Of A Trapezoid

The perimeter of a trapezoid is two times the base length plus two times the side lengths. True or False?

Possible Answers:

True

False

Correct answer:

False

Explanation:

Since the two base lengths area not the same length, you must add them separately and not just multiple one of the by two.

Example Question #2 : How To Find The Perimeter Of A Trapezoid

Set_3

Figure not drawn to scale

Find the perimeter of the trapezoid.

Possible Answers:

Correct answer:

Explanation:

In order to find the perimeter of the trapezoid, you must add up the lengths of all the sides of the trapezoid.

Because the lengths of the trapezoid are in inches, the answer is  

Example Question #1 : Triangles

The base of triangle ABC is \dpi{100} 6\ cm, it's height \dpi{100} 12\ cm. What is the triangle's area?

Possible Answers:

\dpi{100} 36\ cm^{2}

\dpi{100} 72\ cm^{2}

\dpi{100} 18\ cm^{2}

\dpi{100} 30\ cm^{2}

Correct answer:

\dpi{100} 36\ cm^{2}

Explanation:

\dpi{100} Area=\frac{1}{2}\ base\times height
