Suppose the base and height are each multiplied by 1/2 what effect should this have on the area

Simple it will become 1/4 the size that it was.

Step-by-step explanation:

Let the base = b

Let the height = h

Area = 1/2 b*h

Now half both of them.

Area = 1/2 (1/2 b)(1/2 * h)

Area = 1/2 (1/4)*b*h

That quarter should convince you that the area is now 1/4 what it was before the base and height were cut in half.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
