Use pythagoras to find the 3rd length of the triangle:
Square root of 8.5^2-7^2= 4.82 yd
Find the area of the trapezium:
((2+(2+4.82))x7)/2
= 30.87 yd^2
To find the area of the parallelogram you just take away the area of the triangle from the area of the trapezium:
Area of triangle is (4.82x7)/2= 16.87yd^2

Beth's speed was 60 mph.

<h3>What is speed?</h3>

The speed (commonly referred to as v) of an object in everyday use and kinematics is the magnitude of the change in its position over time or the magnitude of the change in its position per unit of time; it is thus a scalar quantity.
The distance traveled by an object in a time interval is divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
Velocity is not the same as speed.

To find what was Beth's speed:
