Step-by-step explanation:
The equation of a trapezoid is (a + b)/2 * h. So let's reverse the equation and divide the area by the height, 112/8 = 14. Now we should multiply it by 2, so we can get what a + b equaled. 28 = 11 + b
b = 17

Number of subset=![2^{n}](/tpl/images/1408/1189/f4831.png)
Her, n is the number of elements in the set.
{p , e , t}
n = 3
Number of subset = 2³ = 2 * 2 *2 = 8
