A. 530 ft^2 b. 500 ft^2 c. 470 ft^2 d. 450 ft^2

OPTION A.

Step-by-step explanation:

Find the length scale factor by dividing the known length of the larger triangle by the known length of the smaller triangle:

Then, the  area scale factor is:

To find the area of the the larger triangle, multiply the area of the smaller triangle by the area scale factor. Then:

So, the option that shows an approximation of the area of the larger triangle is the option A:
