A parallelogram has a base that measures 5 units and a height that measures (x + 6) units. The area of this parallelogram is 20
square units. What must be the value of x?
Choose one answer.
a. x=4
b. x=-2
c. x=5
d. x=15
1 answer:
The answer is
The answer is <span>b. x=-2 </span>
The area (A) of a parallelogram with height h and base b is:
A = b*h
We have:
b = 5
h = x + 6
A = 20
A = b * h
5 * (x + 6) = 20
x + 6 = 20 / 5
x + 6 = 4
x = 4 - 6
x = -2
