Area = 1/2 x base x height The area of a triangle is directly proportional to its base (and also, actually, to it's height). Therefore, any change to the base (or it's height) is directly conferred onto that triangle's area. BY DOUBLING THE BASE OF A TRIANGLE, IT'S AREA TOO WILL DOUBLE.

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

Doubling those two dimensions would quadruple the area. So new area = 4*34 cm2 = 136 cm2

Area of a triangle = base * height / 2 Therefore the base = Area * 2 / height

Area of a triangle = 0.5*base*height

A base is normally a line and therefore has no area; the area of a triangle is half of base x altitude.

Because the area of a triangle = 0.5*base*height

the area of a triangle is half of the base times the height the area of a triangle is half of the base times the height

Area of a triangle = 0.5*base*height

Area of a triangle = 0.5*base*height
