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?
so you find are length times width so 3 times 5 equals 15 usally you then divide by 2 but a trick I use is take how many ever you have and divide by 2 so 200 divide 2 equal 100 so 15 times 100 that's you anwser
