the grid you see below is in the shape of a rectangle. what is the area, in square units, of the shaded part?
Answer
Explanation:
Step1: Count rows and columns
The rectangle has 4 rows and 10 columns of small squares.
Step2: Identify the shaded - part shape
The shaded part is a right - triangle.
Step3: Determine base and height
The base of the right - triangle is 10 units and the height is 4 units.
Step4: Apply area formula for triangle
The area formula for a triangle is $A=\frac{1}{2}bh$. Substitute $b = 10$ and $h = 4$ into the formula: $A=\frac{1}{2}\times10\times4$.
Step5: Calculate the area
$A=\frac{1}{2}\times10\times4 = 20$ square units.
