Question

problem 9: spiral review determine the area of this triangle. 20 square units edit my response

Explanation:

Step1: Identify base and height

Count grid - squares. Base $b = 8$ units, height $h = 5$ units.

Step2: Apply area formula

The area formula for a triangle is $A=\frac{1}{2}bh$. Substitute $b = 8$ and $h = 5$ into the formula: $A=\frac{1}{2}\times8\times5$.

Step3: Calculate the area

$\frac{1}{2}\times8\times5= 20$ square units.

20 square units
