To solve this question, you must divide the trapezoid into a rectangle and two right triangles. Using the Pythagorean Theorem, you would calculate the height of the triangle which is 4. The dimensions of the rectangle are 5 and 4, hence the area will be 20.

You can find the height of a trapezoid by dropping the altitude and using the side of the triangle that you have to find the height using the 45-45-90 triangle method or 30-60-90 triangle method, which will give you the other two sides, including the height

Hopefully that makes sense

Put the numbers in order
6,7,15,36,41,43,47,49

Q1 = (7 + 15) / 2 = 22/2 = 11 <== first quartile
Q2 = (36 + 41) / 2 = 77/2 = 38.5 <== median
Q3 = (43 + 47) / 2 = 90/2 = 45 <== third quartile

difference of largest value and median.....(49 - 38.5) = 10.5

ASHA 777 [7]

Answer:

2 and 4.

Step-by-step explanation:

2 is not a square because a trapezoid does have 4 sides, but the sides are not parallel, or congruent. ↓

4 is not a square because similar to the trapezoid, it does have 4 sides, but is not parallel nor congruent. ↓

Although some people consider a rectangle a square, it is a square and also is not because it has 2 pairs of parallel sides, instead of all 4 sides being parallel.

Hope it helps!
