It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.
Suppose you have a Kohls coupon of $49000 and you want to know how much you will save for an item if the discount is 60 percent.
Solution:
Replacing the given values in formula (a) we have:
Amount Saved = Original Price x Discount in Percent / 100. So,
Amount Saved = 49000 x 60 / 100
Amount Saved = 2940000 / 100
Amount Saved = $29400 (answer).
In other words, a 60% discount for a item with original price of $49000 is equal to $29400 (Amount Saved).
Note that to find the amount saved, just multiply it by the percentage and divide by 100.
