Find the missing side

@marcoduuuh Are you trying?

yes!

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

hey just an idea here take half of seven and than half of 10 and times them together

I got 35?

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

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

17.5!

@marcoduuuh Can you use Pythagoras to find height?

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

that's Pythagoras

yes

hey ash am I missing something here??

10^2+7^2= 149.
sqrt of 149 is: 12.2065556

Nope, it doesn't. ):
