Q:
# Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image below to determine the area of the triangle and how many she can cut out. Triangle with height of 7 inches and base of 14 inches aligned to the left side of a 14 by 14 inch square grid.

Accepted Solution

A:

Hello!

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

[tex] \frac{hb}{2} [/tex]

h is height

b is base

Put in the values you know

[tex] \frac{7 * 14}{2} [/tex]

Multiply

[tex] \frac{98}{2} = 49[/tex]

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Hope this helps!
