Question

Estimate the perimeter and he area of the shaded figure.

Answer 1

Answer:

Perimeter: 6+$9\sqrt{2}$ units

Area: 13.5 $units^{2}$

Step-by-step 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: $\frac{1}{2}$ (b · h)    b = base, h = height

plug- in values, so $\frac{1}{2}$ (3 · 3) is half of 9 which is 4.5.

3 · 4.5 is 13.5

Answer 2

13.5 is the answer/perimeter.
