Answer 2

`\\ \sf\longmapsto Area=30x^2-53x+12`

`\\ \sf\longmapsto Area=30(3)^2-53(3)+12`

`\\ \sf\longmapsto Area=30(9)-159+12`

`\\ \sf\longmapsto Area=270-159+12`

`\\ \sf\longmapsto Area=111+12`

`\\ \sf\longmapsto Area=123`

And

`\\ \sf\longmapsto Base=4x-6`

`\\ \sf\longmapsto Base=4(3)-6`

`\\ \sf\longmapsto Base=12-6=6`

Now

`\\ \sf\longmapsto Area=(1)/(2)bh`

`\\ \sf\longmapsto (1)/(2)6h=123`

`\\ \sf\longmapsto 3h=123`

`\\ \sf\longmapsto h=(123)/(3)`

`\\ \sf\longmapsto h=41`
