Question

Sorry for the weird looking image help me please :)

Answer 1

1 : Go .....

`A= bh \:`

Divided sides by b

`(A)/(b) = h * (b)/(b) \\`

thus ;

`h = (A)/(b) \\`

_________________________________

2 : Go .....

`area = height * length(base) \\`

`45 = h * 9`

Divided sides by 9

`(45)/(9) = h * (9)/(9) \\`

`h = 5 \: ft`

And we're done...
