<h3>Answer: 1</h3>

========================================================

Explanation:

We're given the height in relation to base BC, so we need to find the length of this base. This is the same as finding the distance from B to C.

Turn to the distance formula

$d = \text{Distance from B to C}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y^2)^2}\\\\d = \sqrt{(-2-(-3))^2+(-1-(-2))^2}\\\\d = \sqrt{(-2+3)^2+(-1+2)^2}\\\\d = \sqrt{(1)^2+(1)^2}\\\\d = \sqrt{1+1}\\\\d = \sqrt{2}\\\\$

Coincidentally, the base and height are the same. This won't always be the case.

Now we can find the area of the triangle

$A = \text{Area of triangle}\\\\A = \frac{1}{2}*\text{Base}*\text{Height}\\\\A = \frac{1}{2}*\sqrt{2}*\sqrt{2}\\\\A = \frac{1}{2}*\sqrt{2*2}\\\\A = \frac{1}{2}*\sqrt{4}\\\\A = \frac{1}{2}*2\\\\A = 1\\\\$

The area of the triangle is 1 square unit.

See diagram below.

<h3><u>Question:</u></h3>

Jody is buying a scrap book and designed paper she has 40 dollars and needs at least 18.25 to buy a scrap book each seet of paper cost 0.34 how may sheets of paper can she buy

<h3><u>Answer:</u></h3>

Jody can buy 63 sheets of paper

<h3><u>Solution:</u></h3>

Jody has 40 dollars

Thus, she can spend less than or equal to 40 dollars

She needs at least 18.25 to buy a scrap book

Each seet of paper cost 0.34

Let "s" be the number of sheets of paper

Then,

$18.25+0.34s\leq 40\\\\Subtract\ 18.25\ from\ both\ sides\\\\0.34s \leq 40-18.25\\\\0.34s\leq 21.75\\\\Divide\ both\ sides\ by\ 0.34\\\\s\leq 63.9$

Thus Jody can buy 63 sheets of paper
