Question

Q no. 8 and 9 plzz solve

Answer 1

8. √3² + √3m + √6 = 0

3 + √3m + √6 = 0

(-√6 - 3 )/ √3 = m





9. Let a = length , b = breadth

ab= 6000 (eq 1)

=> (a+20)= 2b

a = 2b - 20


Putting value of a in eq 1

= 2b² - 20b = 6000

b² - 10b = 3000

= b² - 10b - 3000 = 0

b = -50, 60

b = 60 m


Putting value of b in eq 1

a x 60 = 6000

a = 100 m

Therefore length of the garden = 100 m
