Question

problem 10: spiral review determine the area of this triangle.

Explanation:

Step1: Identify base and height

By counting grid - squares, assume base $b = 6$ units and height $h = 6$ units.

Step2: Apply area formula

The area formula for a triangle is $A=\frac{1}{2}bh$. Substitute $b = 6$ and $h = 6$ into the formula: $A=\frac{1}{2}\times6\times6$.

Step3: Calculate the area

$A=\frac{1}{2}\times36 = 18$ square units.

Answer:

18 square units
