The quilt pattern includes 32 small triangles. Each has a base of 3 in. and a height of 1.5 in. Find the amount of fabric used to make the 32 triangles.

Answer 1

well, how do you find the area of ONE triangle whose base is 3 and height is 1.5?

Answer 2

Is this the diagram? @Pepper5

Yes @Directrix

Answer 4

@Pepper5

The area of one triangle can be found by this formula:

A = (1/2) * b * h where b is the length of the base of the triangle and h is the height drawn to that base.

A = (1/2) * 3 * 3/2) = 9/4 square inches as the area of ONE triangle.

To get the amount of material needed for 32 triangles, multiply 32 by (9/4).

You can crank that answer out by hand.

Or, copy and paste "32 times (9/4)=" in the Google search box. The Google calculator will pop up with the answer.
