area of polygons - math

The sixth-grade art students are making a mosaic using tiles in the shape of right triangles. Each tile has leg measures of 3 centimeters and 5 centimeters. If there are 200 tiles in the mosaic, what is the area of the mosaic?

How do I set this up?

Thanks in advance

  1. A = bh/2
    A = (3 * 5)/2
    A = 7.5 sq. cm.

    200 * 7.5 = ?

  10. Area= Base*Height
    A=(3*5)/2
    A=15/2
    A=7.5 sq. cm.
    200*7.5=1500
    Hope this helps

  15. the answer is 7.5 . There are 2 triangle shaped sides that meet that are each 3 centimeters and 5 centimeters long. The formula for finding the area of a triangle is A= 1/2 x bh (base times height). 5 is the base, so you set it up like this: 1/2 x 5 x 3. The answer to this formula is 7.5. There is your answer.
