Using older bros acc this is how much i need be
the shape of nevada can be divided into an almost perfect triangle and almost perfect rectangle. the rectangles dimensions are 320 x 190. the triangles base is only given, the height is not given. the base of the triangle is 305. about how many square miles does nevada cover?

Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.

I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.

Area of the rectangle = Length * width
A = 320 mi x 190 mi 
A = 60,800 sq. mi.

Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.

Total Area = 60,800 + 48,800 = 109,600 square miles.

You need to show the graph
