Doubling the base, but leaving the height unchanged, will double the area.

Doubling the base of a triangle while keeping the height constant will double the area of the triangle. The area of a triangle is directly proportional to its base length, so increasing the base length by a factor of 2 will result in the area being multiplied by 2 as well.
There is no change in the area. Doubling the base and halving the height gives the same area. The formula for area of a triangle is A = bh/2 1/2 (base x height) Example: base 5, height 8 A = (5 * 8)/ 2 = 20 base 10, height 4 A = (10 * 4)/2 = 20
you can cut a triangle directly
Area of a triangle: 0.5*base*perpendicular height
The area of triangle is : 60.0
The area of triangle is : 64.0
