Question

3. A scrap of fabric has the dimensionsshown. What is the area of the scrapof fabric?: 12 m15 m

Answer 1

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 = }(1)/(2)* base* height`

So, this becomes

`\begin{gathered} \text{Area of triangle = }(1)/(2)* base* height \\ \text{Area of triangle = }(1)/(2)*15*12 \\ 2\text{ into 12, we have 6, so this becomes } \\ =15*6 \\ =90m^2 \end{gathered}`

Hence, the answer is 90 square-meters
