Area of Trapezoid = (1/2)*(Sum of Parallels) * height
45 = (1/2)*(10 + 5) * h
45 = 1/2 * 15 * h
45 = 7.5 h
45 / 7.5 = h
6 = h
h = 6 Height is = 6 cm.
The equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4
<h3>Direct and indirect variation</h3>
An indirect variation is also known as the inverse variation
If the variable y is indirectly proportional to x , this is expressed as:
y = k/x
where
k is the variation constant
If the variation constant is -4, then;
y = -4/x
Hence the equations that represent an indirect variation relationship with a constant of variation equal to -4 are y = -4/x and xy = -4
