Question

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?

Answer 1

The Area of a Triangle is 0.5 x Base x Height. The area of one mosaic triangle = 0.5 x 3 x 5 = 7.5. The area of the whole mosaic is : 7.5 x 200 = 1500cm^2. You're welcome.
