A rectangle has 2 diagonals
The answer is actually choice B. To solve for the area of a trapezoid, you would do the formula a+b/2 h.
Probability of heads or tails is .5
so you do (.5)^3 and you get D = 0.125
Answer:Area of triangle is 18cm2
There is a dotted line to show us how to do,we know the dotted means we don’t actually work that part out.
1. The bottom added together = 11,now : (11x6) ÷ 2 = 33cm2.
2.The part where there is a dotted triangle: (6x5) ÷ 2 = 15cm2.
3. 33 - 15 = 18.
