Question

What is the area of a triangle that has a base of 15 1/4 in. and a height of 18 in.?

Elaborate and show your work. Please.

Answer 1

`(1)/(2)`×base×hight

`(1)/(2)`×15
`(1)/(4)`×18

`(1)/(2)`×
`(61)/(4)`×18
137.25 in²

Answer 2

To find the area of a triangle, we can use the formula
`(1)/(2) bh`, where b is base and h is height.

We can then substitute the variables with our measurements. We then end up with an equation of
`(1)/(2) * 15 (1)/(4) * 18`. Well, we can multiply one half with 18 to get 9, and all we need to do is multiply
`15 (1)/(4)` with 9.

We get the grand total of 137.25 inches.
