Answer:

84m

Step-by-step explanation:

First split the shape up. There can be rectangle and then a triangle at the top.

Find the area of the rectangle first:

12 * 4 = 48.

Rectangle area 48m

Now find the area of the triangle at the top:

The base of the triangle is 12. The height would be 10-4 which gives you the height of 6. So, 12 * 6 divided by 2 would give you the area of the triangle.

12 * 6 = 72, 72/2 = 36

Triangle Area 36m

Now add the two areas up: 48 + 36 = 84

So the area of the polygon is 84m

Answer:

$\frac{14}{15}$
$\frac{1}{4}$

Step-by-step explanation:

Given the following equations:

$2\frac{4}{5} \times\frac{1}{3}$
$1\frac{1}{4} \times\frac{1}{5}$

In order to solve the following equations, we convert the mixed numbers into improper fractions and then solve by multiplying the numerators and the denominators by each other.

$2\frac{4}{5} \times\frac{1}{3}$
$2\frac{4}{5} =5\times2=10+4=\frac{14}{5}$
$\frac{14}{5} \times\frac{1}{3}$
$14\times1=14$
$5\times3=15$
$=\frac{14}{15}$

$1\frac{1}{4} \times\frac{1}{5}$
$1\frac{1}{4} =1\times4=4+1=\frac{5}{4}$
$\frac{5}{4} \times\frac{1}{5}$
$5\times1=5$
$4\times5=20$
$\frac{5}{20} \div5=\frac{1}{4}$
$=\frac{1}{4}$

Hope this helps.
