| 3. Find the Area of the triangle.<br> 8.6 yd<br> 10.9 yd

Nitella [24]

Given:

The base of the triangle = 8.6 yd

The height of the triangle = 10.9 yd

To find the area of the triangle.

Formula

The area of a triangle with b as base and h as height is

$A=\frac{1}{2}bh$

Now,

Taking, b= 8.6 and h = 10.9 we get,

$A=\frac{1}{2}(8.6)(10.9)$ sq yd

or, $A= 46.87$ sq yd

Hence,

The area of the given triangle is 46.87 sq yd.

Question<br> Find the distance between the points (-5, 8) and (-3,0).

Temka [501]

To calculate the distance between two points we use this formula:

$\boxed{ \boxed{{d \: = \: \sqrt{(x_2 \: - \: x_1)^{2} \: + \: (y_2 \: - \: y_1)^{2} } }}}$

<h3>We organize the values:</h3>

x₁ = -5
x₂ = -3
y₁ = 8
y₂ = 0

______________________

We apply the values already obtained to the formula to get the distance:

$d \: = \: \sqrt{( - 3 \: - \:( - 5))^{2} \: + \: (0 \: - \: 8)^{2} }$

$d \: = \: \sqrt{( - 3 \: - \: ( - 5))^{2} \: + \: ( - 8)^{2} }$

$d \: = \: \sqrt{( - 3 \: + \: 5) ^{2} \: + \: 64 }$

$d \: = \: \sqrt{ {2}^{2} \: + \: 64 }$

$d \: = \: \sqrt{4 \: + \: 64}$

$d \: = \: \sqrt{68}$

$d \: = \boxed{ \bold{ \: 2 \sqrt{17} \: units}}$

<h2>Answer: </h2>

$\huge{\boxed{ \bold{2 \sqrt{17} \: units }}}$
