    Find the side then use the area formula, \[\frac 1 2 \times base\times \ height\]

    1/2 of 7 is 3.5 and half of 10 is 5 so what is the answer?

    |dw:1358831111900:dw| You need to find the height first, formula doesn't involve hypotenuse's length

    @marcoduuuh Can you use Pythagoras to find height?

    better use a2+b2=c2 may be that would work here
