a trapezoid has one base of 10 inches,an altitude of 6 inches and an area of 51 square inches, find the length of the other base
Inessa [10]

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\\ h=height\\ ---------\\ a=10\\ h=6\\ A=51 \end{cases}\implies 51=\cfrac{6(10+b)}{2} \\\\\\ 51=3(10+b)\implies \cfrac{51}{3}=10+b\implies 17=10+b\implies 7=b

What is the perimeter of the following figure?​
PSYCHO15rus [73]

Answer:

13.4 x 2 = <em>26.8</em>

<em>12.5</em>

HYPOTENUSE:

10^2 + 12.5^2 = 256.25

Square root of 256.25 = around 16

which would equal 256

<em>16 </em>is your hypotenuse.

26.8 + 12.5 + 16 = 55.3 is your perimeter
