Example Question #391 : Ssat Middle Level Quantitative (Math)

Trapezoid

The above diagram depicts a rectangle  with isosceles triangle .  is the midpoint of . What is the ratio of the area of the orange trapezoid to that of the white triangle?

Possible Answers:

More information is needed to answer this question.

Correct answer:

Explanation:

We can simplify this problem by supposing that the length of one leg of a triangle is 2. Then the other leg is 2, and the area of the triangle is 

Since  is the midpoint of  , . Also, since opposite sides of a rectangle are congruent,

.

This makes the trapezoid one with height 2 and bases 2 and 4, so 

The ratio of the area of the trapezoid to that of the triangle is 6 to 2, which simplifies to 3 to 1.

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

Q_10

Find the area of the trapezoid above.

Note: Image not drawn to scale.

Possible Answers:

Correct answer:

Explanation:

The area of a trapezoid is equal to the average of the length of the two bases multiplied by the height.

The formula to find the area of a trapezoid is:  

In this problem, the lengths of the bases are  and  Their average is . The height of the trapezoid is 

Remember: the answer to the problem should have units in cm2 .

Example Question #1 : How To Find The Area Of A Trapezoid

Trapezoid

 

What is the area of the above trapezoid?

Possible Answers:

Correct answer:

Explanation:

To find the area of a trapezoid, multiply one half (or 0.5, since we are working with decimals) by the sum of the lengths of its bases (the parallel sides) by its height (the perpendicular distance between the bases). This quantity is

Example Question #1 : Trapezoids

Find the area of the trapezoid:

Question_7

Possible Answers:

Correct answer:

Explanation:

The area of a trapezoid can be determined using the equation .

Example Question #1811 : Hspt Mathematics

Trapezoid

 

What is the area of the trapezoid?

Possible Answers:

Correct answer:

Explanation:

To find the area of a trapezoid, multiply the sum of the bases (the parallel sides) by the height (the perpendicular distance between the bases), and then divide by 2.

Example Question #1 : How To Find The Area Of A Trapezoid

Trapezoid

The above diagram depicts a rectangle  with isosceles triangle . If  is the midpoint of , and the area of the orange region is , then what is the length of one leg of  ?

Possible Answers:

Correct answer:

Explanation:

The length of a leg of  is equal to the height of the orange region, which is a trapezoid. Call this length/height .

Since the triangle is isosceles, then , and since  is the midpoint of , . Also, since opposite sides of a rectangle are congruent, 

Therefore, the orange region is a trapezoid with bases  and  and height . Its area is 72, so we can set up and solve this equation using the area formula for a trapezoid:

 

This is the length of one leg of the triangle.
