A traffic light hangs t feet from the ground, over a street. A man standing the shadow of the traffic light is h feet tall, and his shadow is s feet long. How far is the man standing from the spot on the street directly under the traffic light?

In the given diagram, . Give the area of to the nearest whole number.

An meteor crashed in the desert and created an oblong shaped crater. Scientists want to find the width of the crater as it is near their research facility. Line segments AC and DE intersect at B making the angles E and D the same. If AB is 2000 meters, BD is 1800 meters, DC is 600 meters and EB is 3600 meters, what is the width of the crater?

In the figure above, line segments DC and AB are parallel. What is the perimeter of quadrilateral ABCD?
