Question

find the area of a triangle with base 2 1/4 and height 4/7 yard. The area is ???yd2

Answer 1

You need to multiply the base and height. The product would be double the area of the triangle.
So what's the product of the base and height?
(hint: You have to change the mixed number to an improper fraction first)

Answer 2

So...
\[\huge 2\frac14 \times \frac47\]

Answer 3

But this isn't readily doable, so, what I want you to do is change
\[\huge 2\frac14 \]into an improper fraction :)
