Answer:
Width is 5 ft, length is 10ft.
Plug in the information given from the problem, in which the width is x, and the length is x + 5.
x(x+5) = x^2 + 5x
(x+4)(x+9) = x^2 + 13x +36
x^2 + 13x +36 - (x^2 + 5x) = 76
Simplify and result in 8x = 40
x = 5, which makes the length 10.

The price of the product before promotional sales was 500,000.
<h3>How to find out what the previous price was?</h3>
To find what the previous price of the product was, we must take into account that we know that 87% of the value is equal to 435,000. So to find out how much the 13% (discount) that the product had is equivalent to, we do the following operation:
435,000 × 100 ÷ 87 = 500,000
So we know that the 13% discount was 65,000
