Question

The area of the entire figure below is 1 square unit.

How can we describe the area of the striped rectangle?

Answer 1

4/15 square unit (0.2667 rounded)

Explanation:

The whole square is one square as

((1/10) x 10 (columns)) multiplied by ((1/3) x 3 (rows)) = 1 multiplied by 1 = 1.

So, with that, the area of the striped rectangles should be:

(1/10) x 4 (columns in the striped area of rects) multiplied by (1/3) x 2 (rows in the striped area of rects) = 0.4 multiplied by 2/3 = 4/15 square unit.
