HELThe police heighten patrols in a certain neighborhood corresponding to Rectangle EFGH, which has vertices E(7, 7), F(1,5), G(2, 2) and H(8,4). Which is closest to the area of
rectangle EFGH?

57.2 units^2

Step-by-step explanation:

The coordinates provided form a parallelogram, not a rectangle.    See the attached image for a diagram of EFGH.  The area of a parallelogram is given by:

Area = (Base) x (Height)

The attachment explains an approach of using right triangles to find the base and height of the parallelogram.  

I'm not confident this was the best approach, so I hope someone would comment if a simpler solution is available.

The answer is in the image 

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The solution is given in the image below

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
