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
<u>multiply</u> the base and <u>add </u>the exponents
6x^3+6y^3+10
2 hours 30 minutes
210 - 30 = 190
190 / 75 = 2.5
Sorry if I'm wrong.
