In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.

$Distance=|-2-(-7)|=5\text{ units}$

So, Laura is correct.

In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.

$Distance=|2-(-9)|=|2+9|=11\text{ units}$

So, Ryan is correct.

Hence, both are correct.

ABCD is a trapezoid with AD = 5 ft, DC = 7 ft, and AB = 15 ft. Find the area of the trapezoid. 30 ft2 33 ft2 44 ft2 55 ft2

Nataly_w [17]

Answer: 33 ft².

Step-by-step explanation:

1. As you can see in the figure attached, the trapezoid is formed by a rectangle and two equal right triangles. The base of each triangle is 4 feet and you know the lenght of the hypotenuse AD, therefore, you can calculate the height by applying the Pythagorean Theorem:

$h=\sqrt{(5ft)^{2}-(4ft)^{2}}=3ft$

2. Now, you can calculate the area with the following formula:

$A=(\frac{B+b}{2})h$

Where B is the longer base, b is the shorter base and h is the height.

Then:

$A=(\frac{15ft+7ft}{2})(3ft)=33ft^{2}$
