The dimensions of a trapezoid are shown below. Which equation could you use to find the Area of the Trapezoid?

Contact [7]

Answer:

See Explanation

Step-by-step explanation:

No trapezoid is attached; so, I will solve on a general note

The area of a trapezoid is:

$Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height$

Using the attached image as a point of reference;

The parallel sides are: AD (6cm) and BD (12cm)

The height is 4cm

So, the area is:

$Area = \frac{1}{2} * (6cm + 12cm) * 4cm$

$Area = 18cm * 2cm$

$Area = 36cm^2$

What is the lenth of MN

alexgriva [62]

MLN is an isosceles triangle

ML = MN

3x = x + 8

Subtract x from both sides

2x = 8

Divide both sides by 2

x = 4

MN = 4 + 8 = 12
