Answer:
x=15
Step-by-step explanation:
If x is 3 and y is 21, then that means that y is 7 times the value of x (21/3=7), or y=7x.
If y is 105, then 105=7x
105=7x
105/7=x
15=x

Option( d ) is the correct one.
Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
