What is the approximate perimeter of the shaded figure above if X = 5 feet, Y = 9 feet, and Z = 4 feet?

anonymous · Answer

18ft

anonymous · Answer

I want to say the answer is 18 feet. You add all of the sides.

anonymous · Answer

18.7 feet?

anonymous · Answer

what kind of shape is it

anonymous · Answer

Just 18ft.

anonymous · Answer

yes you add all sides of that figure

anonymous · Answer

Since none of the measurements were decimals it would be 18 ft.

The answer was 23...

5+4+9+? = perimeter

anonymous · Answer

oh ok then i dont know i thought you were talking what the perimeter was sorry

amistre64 · Answer

how about instead of just typing up answers, we actually try to study thru the material ...

amistre64 · Answer

using the pythag thrm, we can solve for the slanted part

4^2+4^2 = slant^2

16+16 = slant^2

2(16) = slant^2

sqrt(2(16)) = slant

slant = 4sqrt(2)

amistre64 · Answer

i know, and the shaded perimeter has 4 sides to it, its up to you do determine the value of the 4th side using the information given
