Area of a Triangle

The area of a triangle is given by

[tex]A = \frac{1}{2}b*h[/tex]

Let's convert the inches to feet and add it together

width = 4ft + 0.67ft = 4.67ft

height = 3ft + 0.5ft = 3.5ft

Let's substitute this into the formula and solve

[tex]A = \frac{1}{2} b*h\\A = \frac{1}{2}*4.67*3.5\\A = 8.17 = 8.2ft^2[/tex]

The area of the triangle is 8.2ft^2
