Answer:
216 in2
Step-by-step explanation:
the area of the rectangle is
20(12)=240
area of the triangle is
4(6)= 24
so now we subtract, 240-24= 216 in2
228
12x8=96 (times 2= 192)
20-(8+8 or 16)=4
4x12=48
------------------------------
6x4=24 (divided by 2 because it is a triangle=12)
48-12=36
192+36=228
