Question

HELP!
The ratio of areas between two similar triangles is 1:4. if one side of the smaller triangle is 2 units, find the measure of the corresponding side of the other triangle.

Answer 1

(side 1/side 2)^2 = area 1/area 2

let the measure of the bigger side is x, so
(2/x)^2 = 1/4
4/x^2 = 1/4
cross multiply, get
x^2 = 16
x = sqrt(16)
x = 4
