You multiply the numerator and denominator of 3/4 with 3 and multiply 1/3 with 4 on the bottom and top and after you get 36/144 you simplify it and you get 1/4 so thats your answer

Plotting the functions is highly recommended.

For A, the area under $f(x)=3$ over the interval [1, 2] is the area of rectangle with height 3 and width 2 - 1 = 1, so the area is

$\displaystyle\int_1^23\,\mathrm dx=3\cdot1=3$

For B, the area under $f(x)=1-|x-1|$ plotted over the interval [0, 2] is the area of a triangle with height 1 and base length 2, so the area is

$\displaystyle\int_0^2(1-|x-1|)\,\mathrm dx=\frac12\cdot1\cdot2=1$
