Best Answer

You've set up the exact question yourself, multiply 30 by 40. Square feet implies that you have multiplied a foot measurement by a foot measurement, so that should clue you in as to what to do. The answer is 1200.

A building with a height of 40 m casts a shadow that is 30 m long. A statue next to the building casts a shadow that is 6 m long. How tall is the statue?

The statue would be eight meters tall. Set up the ratio 40/x = 30/6 Multiple both sides by 6x to get 40*6 = 30x or 240 = 30x Divide both sides by 30 to get 8=x.


If a regular polygon has exterior angles that measure 30 each how many sides does the polygon have?

We know that the sum of a polygon's exterior angles, one at each vertex, equals 360 degrees. So at each angle extended from each side there is an angle of 30 degrees. If x= number of sides, then 30x = 360. Divide by 30 and x = 12.
