Answer from: cocobelle

Step-by-step explanation:

Area of shape A = $\frac{1}{2}(\text{Base})(\text{height})$

= $\frac{1}{2}(4)(5)$

= 10 square units

Area of shape B = Length × width

= 4×2

= 8 square units

Area of shape C = 5 square units

Area scale factor = $(\frac{\text{Area of image}}{\text{Area of original}} )$

Area scale factor = (Scale factor)²

If scale factor = 2

Area scale factor = 2² = 4

Rule for the dilation,

Area of image = Area scale factor × Area of preimage

Therefore, area of figure A after dilation = 4×10 = 40 square feet

Area of figure B after dilation = 4×8 = 32 square feet

Area of figure C after dilation = 4×5 = 20 square feet

Similarly, we can get areas by different scale factors given in the table.

Scale factor Area of shape A Area of shape B Area of shape C

2 40 32 20

3 90 72 45

10 1000 800 500

$\frac{1}{2}$ 2.5 2 1.25

x 10x² 8x² 5x²
