Answer:
20ft × 17ft
Step-by-step explanation:
(20-x)(23-x) = (20×23) - 120
460 - 43x + x² = 460 - 120
x² - 43x + 120 = 0
x² - 40x - 3x + 120 = 0
x(x - 40) - 3(x - 40) = 0
(x - 40)(x - 3) = 0
x = 3, 40
x = 3
New dimensions:
(23-3) × (20-3)
20 × 17

Answer:
13cm
Step-by-step explanation:
Let the given lengths be the opposte amd adjacent sides of a right triangle'
The missing side will be the hypotenuse
Using the pythagoras theorem;
hyp^2 = 5² + 12²
hyp² = 25 + 144
hyp² = 169
hyp =√169
hyp = 13cm
Hence the missing one is 13cm
