SOLUTION

From the image, the scrap of fabric has the shape of a triangle,

with base 15m and height 12m

Area of a triangle is calculated as

\text{Area of triangle = }\frac{1}{2}\times base\times height

So, this becomes

\begin{gathered} \text{Area of triangle = }\frac{1}{2}\times base\times height \\ \text{Area of triangle = }\frac{1}{2}\times15\times12 \\ 2\text{ into 12, we have 6, so this becomes } \\ =15\times6 \\ =90m^2 \end{gathered}

Hence, the answer is 90 square-meters

This set of ordered pairs is a function (22, 4), (21, 1), (0, 0), (1, 1), and (2, 4).
Mariulka [41]

Answer:

Step-by-step explanation:

You know these ordered pairs are considered a function, because the x intercepts do not repeat themselves. In other words, each input numbers are different. If these ordered pairs were not a function, the x intercept would be repeating. For example,  22 is already a x intercept, (22,4), if 22 was put in as another x intercept like,(22,1) these ordered pairs would not be a function.
