Answer:

The perimeter of one of the trapezoids is equal to
(16+8√(2))\ in

Explanation:

see the attached figure to better understand the problem

we know that

The perimeter of a square is


P=4b

where

b is the length side of the square

step 1

Find the length side of the smaller square


16=4b


b=16/4=4\ in

step 2

Find the length side of the large square


48=4b


b=48/4=12\ in

step 3

Find the height of one trapezoid

The height is equal to


h=(12-4)/2=4\ in

step 4

Remember that in this problem, one trapezoid is equal to one square plus two isosceles right triangles.

Find the hypotenuse of one isosceles right triangle

Applying Pythagoras Theorem


c^(2)=4^(2) +4^(2) \\ \\c=4√(2)\ in

step 5

Find the perimeter of one of the trapezoid

The perimeter is equal to


P=(4√(2) +4+4√(2)+12)\\ \\P=(16+8√(2))\ in
