Example Question #291 : Geometry
Figure not drawn to scale
Find the perimeter of the trapezoid.
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?
Rhombus
Square
None of these
Rectangle
Quadrilateral
Quadrilateral
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 #3 : How To Find The Perimeter Of A Trapezoid
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?
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?
True
False
False
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 #23 : Trapezoids
Figure not drawn to scale
Find the perimeter of the trapezoid.
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 #292 : Geometry
The base of triangle ABC is , it's height . What is the triangle's area?
Example Question #293 : Geometry
What is the area of a triangle that has a base of and a height of
In order to find the area of a triangle, we must use the formula
So the first thing we must do is multiply the base and height.
The next thing we must do is find of through multiplication.
Example Question #3 : How To Find The Area Of A Triangle
Find the area of the triangle:
Example Question #2 : How To Find The Area Of A Triangle
A triangle has an area of 36 in.2. if its base is 6 in., what is its height?
To find the height of the triangle, you must need to plug in what you know (the area and the base of the triangle) into the formula to find the area of the triangle:
Now that you plugged in the area and the base into the formula to find the area of a triangle, you can solve for the height:
Multiply both sides by 2 (the reciprocal of 1/2) to get rid of the fraction
Divide both sides by 6 to find the height
Remember that is the same as
Example Question #294 : Geometry
A triangle has a base that is 8 cm. and a height that is 12 cm. What is the area of this triangle?
To find the area of the triangle, we need to plug in what we know (the base and the height) into the formula to find the area of the triangle:
We can know solve for
