DFC equals 180 because all triangles add up to 180. And their sides are the same so 180/3=60
Answer:
312cm2
Step-by-step explanation:
Area of the triangles:
A =1/2bh
A=1/2(10*12) = 1/2*120=60.
There are two triangles. 60*2=120. 120 is the area of both triangles.
Area of the rectangle:
16*12=192.
120+192=312cm2
60
7:3
7+3=10
60/10=6
6*7=42
6*3=18
42 cars
18 trucks
