The rectangle is 6x4, so that’s easy. that part is 24 square centimeters
the triangle has both a base and a height of 4. basexheight/2 is how you find a triangle, so 4x4/2= 8 square centimeters
the half circle has a diameter of 4, so it has a radius of 2. we will use the formula for the area of a circle with that radius and then cut it in half. 2(pi)r^2=6.283(2)^2=6.283x4=25.132 now we cut that in half 25.132/2=12.566
