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.if there are 200 tiles in the mosaic,what is the area of the mosaic?

Answer 1

Area of a right triangle is equal to (the length times the height) divided by 2

So the area of each tile is (3 x 3) / 2 = 4.5 square centimeters

200 tiles equal 200 x 4.5 = 900 sq cm
