Question

What is the perimeter of quadrilateral EFGH?

Answer 1

54 units

Explanation:

From G to H, use the Pythagorean Theorem:

`3^2+4^2=√(25) =\fbox{5}`

From G to F, just count:

`\fbox{11}`

From H to E, use the Pythagorean Theorem:

`12^2+5^2=√(169)=\fbox{13}`

From F to E, use the Pythagorean Theorem:

`15^2+20^2=√(625)=\fbox{25}`

Now, add up all the answers:

`5+11+13+25=\fbox{54}`
