Question

what time does the area change when sides of a triangle are doubled​

Answer 1

Answer:

The area becomes "four times".

For example, a triangle of base 3m and height 4m has the area of 6m(1/2*3m*4m). When the sides are doubled, i.e., when base is 6m and height is 8m, then the area is 24m(1/2*6m*8m), which is four times of 6m. 

(You could try with other measures too.)
