Januka

Januka and her father were going to the tent. They found that their old tent was torn. Their mother suggested that they sew a tent whose walls would be made of 4 identical isosceles triangles. Their lower side is 2 m long, and the height is also 2 m. Then, find the area of cloth required to make the tent.

Correct answer:

A =  8 m²

Step-by-step explanation:

$$\begin{gathered} n=4 \\ a=2\text{m} \\ h=2\text{m} \\ {A}_1=\frac{a\cdot h}{2}=\frac{2\cdot 2}{2}=2{\text{m}}^2 \\ A=n\cdot A_1=4\cdot 2=8{\text{m}}^2 \end{gathered}$$
