What is the perimeter of the figure

Elanso [62]

Answer:

Perimeter of the figure $=230.66feet$

Step-by-step explanation:

Perimeter of a figure is the sum of all of its sides.

The given figure has all its sides in mixed fraction:

Making the sides in proper fraction:

$60\frac{5}{6} feet$ $=\frac{(60*6)+5}{6}=\frac{365}{6} feet$ = $60.83feet$

$59\frac{1}{3} feet$ $=\frac{(59*3)+1}{3}feet$ $=\frac{178}{3} feet$ $=59.33feet$

$56\frac{1}{6}feet$ $=\frac{(56*6)+1}{6}= \frac{337}{6}feet$ $=56.17feet\\$

$54\frac{1}{3} feet$ $=\frac{(54*3)+1}{3}=\frac{163}{3} feet$ $=54.33feet$

Adding all the Sides to find the perimeter:

$=60.83+59.33+56.17+54.33\\\\=230.66feet$

The perimeter of the figure $=230.66feet$

Need help with this

likoan [24]

Answer:

The answer is h = 2A/(b+c) .

Step-by-step explanation:

You have to move all the unrelated terms to the other side by making h the subject :

$A = \frac{1}{2} (b + c)h$

$A \div \frac{1}{2} = \frac{1}{2} (b + c)h \div \frac{1}{2}$

$2A = (b + c)h$

$2A \div (b + c) = (b + c)h \div (b + c)$

$\frac{2A}{b + c} =h$

$h = \frac{2A}{b + c}$
