Problema Solution
two similar triangles have corresponding sides with lengths 3 and 9. if the area of the first triangle is 12, what is the area of the second triangle?
Answer provided by our tutors
The ratio of sides of triangle is 3:9=1:3
therefore the area of similar triangle should be also 1:3
let the area of second triangle is x.
ratio should be 1:3 = 12:x
=>1/3 = 12/x
=>12/x = 1/3
=>12 * 3 = x
=>x= 36
the are of the similar triangle is 36
