Answer:
80
Step-by-step explanation:
area of trapezoid is given by formula
Area = 
h
where a is one base, b is another base and h is height
In given case, we have
a= 7+7+3 = 17
b= 3
h= 8
Substituting the values
Area= 
x 8
= 
x 8
= 10 x 8
= 80

Answer:
the first one
Step-by-step explanation:
Answer:
81 cm square
Step-by-step explanation:
The answer would be -1/12 .
2/3 - -3/4=-1/12
2/3=8/12
-3/4=-9/12
8/12- -9/12=-1/12
That would be <u><em>1/6</em></u>. To find this, first, move the decimal two places to the right, and put that number over 100:
<u />16.666.../100
This fraction can then be simplified by dividing both sides by 16.666... to get 1/6.
In reality, the fraction 1/6 simply cannot be expressed as a decimal, but many people just put 0.1666666... because it is a pretty good approximation.
Hope this helps!
