Use the formula for the area of a triangle. One inch is roughly 2.54 centimeters.
≈0.31in^2
We want to find the area of the triangle in square inches. Notice that the base and the height are given in centimeters. Let's convert them to inches first and then we can determine the area.
We can use a conversion factor to convert the units. Notice that both the base and the height are equal to 2 cm, so we just have to convert 2 cm to inches. To cancel out centimeters, we will use the conversion factor 1in2.54cm.
Multiply by 1in/2.54cm
a*b/c= a* b/c
Cross out common factors
Simplify quotient
a * 1=a

To calculate the area of a triangle we can use the following formula. A=1/2bh Here b is the length of the base and h is the height. We already know that both base and height are equal 0.79in. Let's substitute these values in the formula.
b= 0.79, h= 0.79
1/b* a = a/b
