Answer:
the area of the triangle is 17.4cm^2
Step-by-step explanation:
Finding the area of a triangle
an isosceles triangle has two sides of equal length.
therefore to get the base of the triangle :
we need to subtract the lengths from he perimeter
30-12-12
= 6
<u>the base of the triangle is 6 cm</u>
<u></u>
<h3><u>area of a triangle</u></h3>
formula :
<h3><u>getting the height of the triangle:</u></h3>
we make use of one side of the triangle , half the base. this creates a right angled triangle
we can make use of the formula
were c is the hypotenuse of 12 cm
a is the adjacent of base (6/2) = 3 cm
and b is the height
b = 11.6 cm to 3sf
<u>the height is 11.6cm.</u>
<u></u>
<em>area of the triangle is :</em>
1/2 * 3 * 11.6
<u>= 17.4 cm^2</u>
<u />
<u>the area of the triangle is 17.4cm^2</u>
It has been estimated that every year 20,000 species are going extinct and 72 species are going extinct on an average day.
<h3>What are species?</h3>

If you would like to know how much is 45 miles per hour in feet per minute, you can calculate this using the following step:
1 mile per hour = <span>88 feet per minute
45 miles per hour = 45 * 88 feet per minute = 3960 feet per minute
Result: 45 miles per hour is 3960 feet per minute.
