Question

a sail on a boat is shaped like a triangle as shown. what is the area of the sail? show your work.

Explanation:

Step1: Recall area formula

The area formula for a triangle is $A=\frac{1}{2}bh$, where $b$ is the base and $h$ is the height.

Step2: Identify base and height

From the figure, the base $b = 4$ m and the height $h=3.7$ m.

Step3: Calculate the area

Substitute $b = 4$ and $h = 3.7$ into the formula: $A=\frac{1}{2}\times4\times3.7$. First, $\frac{1}{2}\times4 = 2$, then $2\times3.7=7.4$ $m^{2}$.

Answer:

$7.4$ $m^{2}$
