How much units squared is this shape

kirill [66]

The shape is already split into 3 different shapes, so you can find the area of each of those shapes and add them together.

Triangle 1 : 2 · 2 · .5 = 2 units²

Square : 2 · 2 = 4 units²

Triangle 2 : 4 · 2 · .5 = 4 units²

2 + 4 + 4 = 10 units²

Answer:

The answer as a mixed number is $=15\frac{3}{4}.$

Step-by-step explanation:

Given:

5 1/4 ÷ 1/3.

Now, to solve as a mixed number in simplest form.

$5\frac{1}{4} \div \frac{1}{3}$

<em>Now, changing the mixed fraction into improper:</em>

$=\frac{21}{4} \div \frac{1}{3}$

So, to solve we change the division into multiplication.

Thus, R.H.S of the fraction will get reverse:

$=\frac{21}{4} \times \frac{3}{1}$

$=\frac{63}{4}$

<em>Now, changing the improper fraction into mixed:</em>

$=15\frac{3}{4} .$

Therefore, the answer as a mixed number is $=15\frac{3}{4} .$
