Question

the grid you see below is in the shape of a rectangle. what is the area, in square units, of the shaded part?
answer attempt 1 out of 2
$a = \square$ units$^2$

Explanation:

Step1: Count shaded full squares

Count all fully shaded squares: 28

Step2: Count half-shaded squares

Count half-shaded squares: 8. Each equals $\frac{1}{2}$ square unit.

Step3: Calculate half-square area

Total area from half-squares: $8 \times \frac{1}{2} = 4$

Step4: Sum total shaded area

Add full and half-square areas: $28 + 4 = 32$

Answer:

32
