A square has an area of 25. If it is dilated by a scale factor of 2, what is the new area?
I think it's 1, is that right?
if a square has an area of 25 then it is a 5x5 square. If it is scaled x2 then it would be 10 x 10 with an area of 100.
I pretty sure 100 is the new area because isn't dilated mean it's gotten bigger by 2 so you take your area and times it by 4 I'm confused with wether it's bigger or smaller. need more info
The new area of the square after dilation is 100. This is because area is proportional to the square of the linear dimensions, which means that if the linear dimensions are doubled, the area is increased by a factor of 2 =4. 25 4 = 100.
