Question

Estimate the perimeter and he area of the shaded figure.

Answer 1

13.5 is the answer/perimeter.

Answer 2

Perimeter: 6+
`9√(2)` units

Area: 13.5
`units^(2)`

Explanation:

I wasn't sure what to estimate to...

for perimeter use:
`a^(2) +b^(2) =c^(2)`

I noticed that the trapezoid was made up of 3 identical triangles, so find the area of one of them times 3

one triangle area:
`(1)/(2)` (b · h) b = base, h = height

plug- in values, so
`(1)/(2)` (3 · 3) is half of 9 which is 4.5.

3 · 4.5 is 13.5
