Answer 1

29 bois

Explanation:

Answer 2

Total increase in height is 31.04 %

Step-by-step explanation:Let initial height be x.

Height increased last year= 17% of x = 0.17x

so last year height = x +0.17x = 1.17x

Height increased this year = 12%

so increase in this year height = 12% of 1.17x = (0.12)(1.17x)

= 0.1404x

Height of this year = 0.1404x +1.17x = 1.3104x

total increase = 1.3104x - x = 0.3104x

% increase =
`(increase )/(initial) (100)`

=
`(0.3104x)/(x) (100)`

= 31.04
