Answer:
D
Step-by-step explanation:
28×14=392, which generally already gives you the answer. But the extra area is a trapezoid so we do 4+6=10×2(height)=20, but we have to divide by two since its a trapezoid giving us 10. So 10+392=402
Answer:
Yes, because P = 2x +2(12)
Step-by-step explanation:
As the formula for perimeter is 2(L+B).
Let L=x=18
B=12
Then, perimeter, P=2(18+12) = 2(30) = 60
Hence, we get the perimeter as 60 units.
Answer:
40°
