The perimeter is the length of the outside edge. Imagine you start walking around the edge of that shape, starting in the bottom left corner and walking up first.
You’d walk 9 yd, turn right walk 19 yd, turn right walk 9 yd, turn right walk 4 yd, turn right walk 6 yd, turn left walk 11 yd, turn left walk 6 yd, turn right walk 4 yd and be back to where you started.
How far did you walk?
9+19+9+4+6+11+6+4 = 68 yds
Substitute b in the expression
4^1•4^5= 4^6= 4,096
In a triangle, if the sum of the squares of 2 shortest sides is less than the square of the third side, (as is the case here), the triangle is obtuse.
So, IF a and b are the 2 shortest sides then this is true.

This one would be b for you to have the right amswer
I think u would just do the work and add the decimal in
