In the first case, the area will remain the same. In the second case, the area will doubled.

The area gets doubled.

If the linear dimensions are doubled, the area is multiplied by (2)2 = 4 .

The area doubles if the base stays the same.

The area should increase.

The area is multiplied by 4, not doubled.

The area of the triangle would double

If the base stays the same, the area is also doubled.

The area gets doubled.

The exact same as the original triangle.

The area doubles if the base stays the same.

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

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.
