2012 AMC 10A Problem 2

Question

A square with side length

8

is cut in half, creating two congruent rectangles. What are the dimensions of one of these rectangles?

2 \text{ by } 4

2 \text{ by } 6

2 \text{ by } 8

4 \text{ by } 4

4 \text{ by } 8

One side of each rectangle stays

8

The other side is half of the square side length

Note that the one of the sides remains the same as the original square.

This means that one dimension is

8.

The other dimension is the original side cut in half, which is

4.

Thus, E is the correct answer.
