Answer 1

Let's take this in steps:

For part(a):

--> write equation to get 'h'

--> area of triangle is 18

--> area of the triangle is one-half times base times height

--base: 6 cm

--height: h +1

`18=(1)/(2) *6*(h+1)\\\\` <==equation

By solving this equation we get this

`18=3(h+1)\\\\18=3h+3\\\\3h=15\\\\h=5`
