The answer is 15
To find the answer set up an equation like this
a2 + b2 = c2 (2 means squared)
Here we are trying to find the value of a so we know the values of b and c.
a2 + 20(squared) = 25(squared)
20 squared equals 400
25 squared equals 625
a2 + 400 = 625
Subtract 400 from 625 which equals 225.
Now we find the square root or closest square root of 225.
The square root of 225 is 15. 15 x 15 = 225
Answer: Completing the square, means
adding ( half the coefficient of the x- term )² to both sides, that is
( )² is added to both sides

ur pretty btw
The answer is the 64 square inches.
-The area of A is 647 beacuase 16*12 is 192 and 13*35 is 455 and 455+192 is 647.The perimeter is A is 120 because 16+25+12+19+35+13 is 120.
-The area of B is 192 because 8*12+8*12 is 192.The perimeter of B is 70 because 8+12+8+7+8+12+8+7 is 70.
