Equation a^2 + b^2 = c^2
c = longest side, unknown
The answer is D.
12^2 + 10^2 = c^2
Answer:
Step-by-step explanation:
we are given a trapezoid
we want to figure out the area
remember that,
where a and b represent the parallel lines and h represents the height
we get from the pic that a and b are 5 and 15 respectively and h is 7
so substitute:
simplify addition:
simplify division:
simplify multiplication:
since we multiply two same units we of course have to use square unit
hence,
It simplifies to the proper fraction 14/15 so it cannot be a mix number
hope this helps !!
