Question

How do you find the area with only this information?

Answer 1

Assuming each segment is 1 unit

$c^2=a^2+b^2 \\ \\ c = \sqrt{a^2+b^2}$

F.
a = 4
b = 2
$c= \sqrt{4^2+2^2} \\\\c= \sqrt{16+4} \\\\c= \sqrt{20}$

G.
a = 4
b = 1
$c= \sqrt{4^2+1^2} \\\\c= \sqrt{16+1} \\\\c= \sqrt{17}$

H.
the length: 4units

I. 
a = 3
b = 1
$c= \sqrt{3^2+1^2} \\\\c= \sqrt{9+1} \\\\c= \sqrt{10}$

The correct answer is "G"
