Math problems help

Give, the parallelogram ABCD in that FBED is a square. Calculate the perimeter of ABCD if BD = 8√2 and AB = 10.

Are you thinking how to get solve geometry answers


a) 24 units
b) 36 units
c) 48 units
d) None of the above
Answer: geometry homework help free
Since FBED is a square, BF = FD and Triangle BFD is a 45-45-90 triangle.

Since Triangle BFD is a 45-45-90 triangle, s = 8. Then AF can be found solved geometry problems with the Pythagorean Theorem.

a2 + b2 = c2 --> a2 + 82 = 102 --> a2 = 36 --> a = 6 --> AF = 6

= AB + BC + CD + DA = 10 + 14 +10 + 14 = 48 units
