Question

Hien would like to estimate the area of Nevada using a trapezoid. She uses the dimensions shown as approximations. What is the approximate area of Nevada?

Answer 1

Answer: 110400 sq. mi.

Answer 2

110400 sq. mi

Explanation:

The area is approximated by a rectangle (207 x 320) sq. mi.

AND a triangle with a base of 320 mi and height = (483-207)=276 mi.

So total approximate area

=207*320 + (1/2)320(276)

=66240+44160

=110400 sq. mi.
