Since the area is (length of base)*(height)/2 {call these dimensions B & H)
A1 = B*H/2
With dimensions doubled, A2 = (2*B)*(2*H)/2 = 4*B*H/2 = 4*A1.
By not simplifying to 2*B*H, it's easier to see that it is four times the original area.
It is 4 times because the two length dimensions are multiplied, and 2 * 2 = 4.

What is the area and perimeter of a triangle if its dimensions are doubled?
Area is quadrupled (*4) and perimeter is doubled.
What happens to the area of a triangle when the base is doubled and the height remains the same?
The area gets doubled.
What happens if the base of a triangle is doubled?
If the altitude is not changed, the area would be doubled.
If the height and the base of a triangle are doubled what happens to the area?
If the linear dimensions are doubled, the area is multiplied by (2)2 = 4 .
What is the effect on the area of a triangle if the base is doubled and the height in cut in half?
you can cut a triangle directly
If the sides of a triangle are doubled then the area becomes?
If the sides of a triangle are doubled then the area becomes quadrupled (four times as large).
How does the area of a rectangle change when its dimensions are doubled?
the area should double also Answer 2 The area will quadruple. Imagine a square with sides 1 x 1. If you doubled the length of the sides you'd have a square of 2 x 2. You'd be able to get four 1 x 1 squares inside that.
If the base and height of a triangle are doubled how is its area changed?
The area is multiplied by 4, not doubled.

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

If the base of a triangle is doubled and height is halved its area will be?
The exact same as the original triangle.
Why does the volume quadruple when the radius of a cylinder is doubled?
The volume is Base x height; the Base area is the same as the formula for a circle - which is proportional to the square of the radius. For example, if you double the radius (or the diameter, or the circumference) of a circle, its area will quadruple.
