Answer:

a=12 and b=6

Explanation:

SORRY IF CONFUSING

The formula for the area of a triangle is 1/2 times base times height.

So for part a it would be 6x4x(1/2)

Which equals 12

For part b the height is 3 and the base is 4

The equation would be 4x3(1/2)

Another way to solve part be is (helpful for problems where you don't know the base of height)

Make a square around the triangle

The dimensions of the square are 3 by 7

The square makes two triangles to solve the area of

Triangle 1 is 3x3(1/2)=21/2

Triangle 2 is 7x3(1/2)=9/2

Now you subtract the area of the two triangles from the square to get the area of the original triangle

21-(21/2)-(9/2)

Which equals 6
