Question

the area of a triangular sail is given by the expression 1/2bh, where b is the length of the base and hi is the height. What is the area of a triangular sail in a model sailboat when b=12 inches and h=7 inches?

Answer 1

Area= 1/2 b xh
Sooo= 1/2 x 12 x 7= 42

Answer: 42 inches squared

Answer 2

Answer:

42 square inches.

Step-by-step explanation:

The given expression for the area of the triangular sail is $\frac{1}{2}bh$

Here b is the length of the base and h is the height.

Now, we have to find the the area of a triangular sail in a model sailboat when b=12 inches and h=7 inches.

Substituting these values in the above expression to find the area of the triangular sail.

$A=\frac{1}{2}\times12\times7\\\\A=6\times7\\\\A=42\text{ square inches}$

Therefore, the area of  triangular sail in a model sailboat when b=12 inches and h=7 inches is 42 square inches.
