stira [4]

Answer:

308025 times larger

Step-by-step explanation:

The polygon BBB is a scaled copy of polygon A using a scale factor of 555.

This means for every length of polygon AAA, polygon BBB is 555 times larger.

Recall area is in L^{2}.

Area of polygon BBB = (scale factor)^2 multiplied by area of polygon AAA

Since the scale factor is 5

Area of polygon BBB = (555^2) * Area of polygon AAA

Area of polygon BBB = 308025 times the area of polygon AAA

Hope I have been able to help.
