The answer is (A) 380.
The missing side is x more then 70.
To get the value of x, let us form a right triangle on the right side of the figure, which its sides are 60 and x and the hyp is 100. This is a right triangle with ratio 3:4:5. So side x to 60 is in ratio 4 to 3.
Hence, x=80 and the perimeter is 60+70+100+150=380.

Diagram can be cut into a rectangle and a right triangle.
Rectangle with sides 60, 70 and Right triangle with sides 100, 60 and one side unknown. Let that side be x.

Pythagorean Theorem to find x:
\(x^2\) + \(60^2\) = \(100^2\)
\(x^2\) = \(100^2\) - \(60^2\) = 6400
x = \(\sqrt{6400}\) = 80

Perimeter = 60 + 70 + 100 + 80 + 70 = 380
Answer A...

Draw a perpendicular line as follows:


From here, we have two different ways to find the value of x

Approach #1: Recognize that 60 and 100 are each 20 times the lengths of the basic 3-4-5 right triangle.
That is (20)(3) = 60 and (20)(5) = 100
So, x = (20)(4) = 80

Approach #2: Apply the Pythagorean theorem
We get: 60² + x² = 100²
Simplify: 3,600 + x² = 10,000
Subtract 3,600 from both sides to get: x² = 6,400
Solve: x = 80

At this point we can find the perimeter....

Perimeter = 60 + 70 + 100 + 80 + 70 = 380

Answer: A

Cheers,
Brent

is it a 6-8-10 triangle since 60-x-100? therefore x = 80?

just over 2 minutes using pythagoreum :/
