If the area of the squares is the same, they must have the same lenght.

Choice A is 3 times AB.

Choice B can be found by tracing a triangle from A to E. Finding the hypothenus of one side AB and another side 2AB. Thus its \sqrt{5}*AB which is less than 3AB

Draw it! You should end up with two squares oriented the same way touching at C. The squares have the same area, so their sides must be the same length. Plug in a side length for the squares to simplify the comparison—try 2. A square cut in half along its diagonal yields a pair of 45-45-90 triangles, so these two squares with sides of 2 each have diagonals of \(2 \sqrt{2}\) Diagonals AC and CE connect to form segment AE. Quantity A is 3 × 2 = 6, and Quantity B is \(2 \sqrt{2}+ 2 \sqrt{2} = 4 2 = 4 (1.4)=5.6\)

A is the answer

if we know ∠bcg and ∠acf are 90..then ∠bcd and ∠gcf are also 90...change your dig. accordingly, you'll see.
