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:

n=4 a=2 m h=2 m  A1=2a h=22 2=2 m2  A=n A1=4 2=8 m2
