Answer and Step-by-step explanation:

$First, ~multiply~base~and~height.~In~our~case~the~base~is~30~inches~and$ $the~height~is~12~inches.$ $Then,~we 'll~take~16~inches~and~multiply~it~with~12~inches$

So, it'll be :

$30~inches$ × $12~inches$ $=360~inches$

$16~inches$ × $12~inches=192~inches$

$Now,~that~we've~got~ 360 ~and~ 192~ as~ our~ answers ~we ~add~ them ~up..$

Like this :

 $360+192=552$ 

 $And,~that's~our~final~answer!-522~in^2$
