The formula for the area of a triangle is 1/2*b*h
The best thing to do is to multiply the answers then half them.
7*12= 84
84/2= 42
Therefore, the area is 42cm2

I need help solving this problem

Answers

let's firstly convert all the mixed fractions to improper fractions and then sum them up.

$\bf \stackrel{mixed}{4(1)/(12)}\implies \cfrac{4\cdot 12+1}{12}\implies \stackrel{improper}{\cfrac{49}{12}}~\hfill \stackrel{mixed}{2(1)/(4)}\implies \cfrac{2\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{9}{4}} \n\n\n \stackrel{mixed}{3(2)/(3)}\implies \cfrac{3\cdot 3+2}{3}\stackrel{improper}{\cfrac{11}{3}} \n\n[-0.35em] ~\dotfill$

$\bf \cfrac{49}{12}+\cfrac{9}{4}+\cfrac{11}{3}\implies \stackrel{\textit{using an LCD of 12}}{\cfrac{(1)49+(3)9+(4)11}{12}}\implies \cfrac{49+27+44}{12}\implies \cfrac{120}{12}\implies 10$

You add the base and to sides which will equal 10 5/12
