Answer:

Step-by-step explanation:
We want to express 3⅓ as a percentage.
Let us first of all rewrite 3⅓ as decimals to obtain:

To express this as a percentage, we multiply by 100%

This multiplies to give us:

In a binary number, each digit can have only one of two possible values : 0 or 1.
In the isosceles trapezoid ABCD, draw two perpendiculars AM and BL from A and B to the side CD.
Now, LM = BA = 5 m
CD = CL + LM + MD
= CL + 5 + CL (CL = MD)
= 2CL + 5
But, CD = 11
Therefore, 2CL + 5 = 11
2CL = 11 - 5
= 6
CL = 6/2 = 3m
MD = 3m
Now, consider the right triangle AMD.
We have,

= 
= 16 - 9
= 7
Hence, height of the isosceles trapezoid = AM =
