The formula of area of triangle is

where b is the base and h is the height .
First we need to convert the mixed fraction to improper fraction, and on doing so we will get

Substituting the values of A and b, we will get

(1/2)bh =A
(1/2) 7 x 12 = 42
(1/2) 84 = 42
42 = 42
H = 7
B= 12
Hope this helps :)
