Answer:
The area of triangle is 49 in² and She can create only 4 triangles.
B is correct.
Step-by-step explanation:
Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches.
In a square grid of 14 inches one triangle already drawn.
If we see the figure.
Base of triangle is 14 inches and Height of triangle is 7 inches.
Formula:
\(\text{Area of triangle }=\dfrac{1}{2}\times B\times H\)
\(\text{Area of the given triangle } =\dfrac{1}{2}\times 14\times 7=49\text{ in}^2\)
If we extend the height to opposite side of square and join the vertex of square to the vertex of given triangle.
We will get 3 new triangle of same area because their base and height are same.
Please see the attachment for figure of four triangle.
Hence, The area of triangle is 49 in² and She can create only 4 triangles.
