What is the area of this trapezoid?
A. 44 n^2
B. 64 n^2
C. 168 n^2
D. 192 n^2

192 in

Step-by-step explanation:

we know that

[the area of the trapezoid]=[area rectangle]+2*[area triangle]

[the area of the trapezoid]=[14*12]+2*[12*2/2]=192 in²

the answer is 192 in²

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
