The right triangle given below was drawn using a scale factor of 1/15. Each small square on the grid has a side length of 2 inches.
The length of the base of the given triangle is how many inches?
The height of the given triangle is how many inches?
Therefore, based on the given right triangle, the area of the original triangle is how many square inches?
To find the length of the base of the given triangle, we count the number of small squares along the base.
We see that the base has a length of 9 small squares, so the length of the base is 9 * 2 = 18 inches.
To find the height of the given triangle, we count the number of small squares along the height.
We see that the height has a length of 6 small squares, so the height of the triangle is 6 * 2 = 12 inches.
Therefore, the area of the original triangle is (1/2) * base * height = (1/2) * 18 * 12 = 108 square inches.
