Answer:
The answer would be 8.1
Step-by-step explanation:
For the smaller triangle, you use the pythagorean theorem. a squared + b squared = c squared.
To find one of the legs, you do 5 squared - 3 squared = b squared.
25 - 9 = b squared. (BD)
16 = b squared
4 = b
Now for the bigger right triangle. You still use the same tactic.
7 squared + 4 squared = c squared (which is AB)
49 + 16 = c squared
65 = c squared
That means c would equal: square root of 65, which is 8.0622577483 which rounds to 8.1
The product of this is 81
Simplify the right hand side:
Expand the left hand side:
Subtract 2x from both sides:
Divide both sides by 4:
Answer:
48
Step-by-step explanation:
8 squares=32
8 half squares=16
32+16=48
There are 4 sides to a 8 whole squares 8*4=32
There a 2 sides to 8 half squares 8*2=16
