What is the perimeter of trapezoid jklm? + units 2 + + units 9 + units 9 + + unitsanswer is d

For the perimiter of the trapezoid you need the length of all four sides, and as the left and right sides are diagonal you use the pythagorean thereom to solve for them. This theorem is a^2+b^2=c^2 as a is vertical, b is horizontal, and c is the diagonal. so for the right side we have 1^2+2^2=c^2 so c^2=5 and c=sqrt(5). for the left side we have 1^2 + 1^2 = c^2 so c = sqrt(2) so we take the top, 3, the bottom, 6, and the sides, sqrt(2) and 5, and add them to get 9 + sqrt(2) + sqrt(5) so D
