The base of a parallelogram is reduced to half of its original size, and its height is increased by six times. The area of the parallelogram is () The bottom of the parallelogram is reduced to half of the original, and the height is increased by 6 times. The area of the parallelogram is ()

Let the original bottom edge be a and the height be H
Original area = ah
Current area = 0.5A * 6h = 3ah
So the area is three times the original
Hand only,

When the base of the parallelogram is expanded to three times its original height and reduced to one sixth of its original height, its area will be 18 square centimeters. What is the original area of the parallelogram?

18 / 6 / 3 = 36 (square centimeter)

Five out of seven plus a few equals minus one

5/7 + x = -1
x = -1 - 5/7
= -12/7
