Help me answer this question

7m

Step-by-step explanation:

1. find ratio of small to large triangle (6:18 = 1:3 / 8:24 = 1:3)

2. find blank side of smaller triangle (if ratio is 1:3 then take the large triangle side that matches the smaller unknown side and divide by 3 to size down the line to find unknown side)

Answer = 7m

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

a is the right answer
