Question

Construct a word problem on quadratic equation, such that one of its answers is 20 (years, rupees, centimeter, etc.). Also, solve it.

Answer 1

Area = length × width

x(x + 8) = 560

x² + 8x = 560

x² + 8x – 560 = 0

(x + 28) (x – 20) = 0

x = –28

x = 20

The dimensions of the garden are 20 cm (width) and 28 cm (length).
