Question

what is the area of the triangle? units²

Explanation:

Step1: Recall triangle area formula

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$.

Step2: Identify base and height

From the diagram, the base (the perpendicular side) is 4 units, and the height (the vertical side) is 14 units.

Step3: Substitute into formula

Substitute base = 4 and height = 14 into the formula: $A = \frac{1}{2} \times 4 \times 14$.

Step4: Calculate the area

First, multiply 4 and 14: $4 \times 14 = 56$. Then, multiply by $\frac{1}{2}$: $\frac{1}{2} \times 56 = 28$.

Answer:

28
