Shalonda notices that when she stands next to the flagpole, she casts a shadow that is 8 feet long and that the flagpole casts a shadow that is 28 feet long. Little Shalonda is 4 feet tall. How tall, to the nearest foot, is the flagpole?
step by step on how to do it?

Seet up a proportion of Shadow/height for each object. So Shalonda would be 8/4 and the flagpole would be 28/x. so 8/4 = 28/x. Cross multiply and divide. (28 X 4) / (8x) or 112/8 = x. So the pole is 14 feet tall which makes sense if her shadow is twice as long as she is tall, so is the flagpole's.
the pole is 69 feet
also 420 ft will work
