Question

the area of the entire figure below is 1 square unit.
how can we calculate the area of the striped region?
choose 1 answer:
a (\frac{1}{4} \times \frac{1}{5})
b (\frac{3}{5} \times \frac{1}{4})
c (\frac{2}{3} \times \frac{3}{5})

Explanation:

Step1: Identify column fraction

The striped region is in the left $\frac{3}{5}$ of the 5-column grid.

Step2: Identify row fraction

The striped region is in the top $\frac{1}{4}$ of the 4-row grid.

Step3: Calculate striped area

Multiply the two fractions to get the area.
$\frac{3}{5} \times \frac{1}{4}$

Answer:

B. $\frac{3}{5} \times \frac{1}{4}$
