Answer:
C.
Step-by-step explanation:
that is the correct answer
Use the triangle formed by the height of the trapezoid to find the lengths of the two sides of the trapezoid and the length of b2:
tan(60)=oppositeadjacent . Adjacent=5tan(60)=2.89 cm.
This finds the base of the triangle, which can be added twice to b1 to find b2: b2=8+2.89+2.89=13.78 cm.
Now, use the same triangle to find the length of the sides.
sin(60)=oppositehypotenuse . Hypotenuse=5sin(60)=5.77 cm.
Lastly, add all of the lengths together: b1+b2+2(l)=8+(2.78+2.78+8)+2(5.77)=33.32 cm.
Answer:
Width equals 11, and length equals 12.
Step-by-step explanation: It is helpful to memorize your multiplication tables up to 12. I personally couldn't figure out a formula for this, but I knew that 12 x 11 equals 132, and the length is greater than the width, so length is 12 and width is 11. Hopefully somebody else can figure it out. P.S. I meant the formula, not the answer, my answer is correct.
