Angela makes a pillow in the shape of a wedge to use for watching tv. the pillow is filled with 121212 feet^3 3 start superscript, 3, end superscript of fluffy material. what is the length of the pillow? feet

the area of the trapezoid is given by (b1 + b2)/2 * height

where b1 and b2 are the lengths of the two parallel sides

area = (b1+b2)/2 * height

area = 144

height = 12

144 = (b1+b2)/2 * 12

12 = (b1+b2)/2

the length of the median of the trapezoid is defined as the average of the two sides which is nothing but (b1 +b2)/2

length of the median = (b1+b2)/2 = 12 feet

length of median = 12 feet

16 is the absolute value
