The formula for finding area of a triangle is:
The base is 8 feet. The area is 48 ft². Put that into the formula:
Remember that you have to multiply the base × height by , which is the same as dividing by 2. To find the height, you need to multiply the area by 2, instead of dividing.
That means the base × height is equal to 96. You already know the height. To find the base, divide the (base × height) by the height. The height is 8.
That means the base of the triangle is 12 ft
<h3>CHECK</h3>
Base = 12
Height = 8
Put that into the formula:
✔
BASE = 12 ft
The cost of 1 glass would be £4
An ordered pair such as (3,-1), is a shorthand way of writing two variables, such as x = 3 and y = -1. The order of the numbers in the pair is important: x always comes before y.
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses.
It helps to locate a point on the Cartesian plane for better visual comprehension.
The numeric values in an ordered pair can be integers or fractions.
Ordered Pair = (x,y)
Where, x = abscissa, the distance measure of a point from the primary axis “x”
And, y = ordinate, the distance measure of a point from the secondary axis “y”
In the Cartesian plane, we define a two-dimensional space with two perpendicular reference lines, namely x-axis and y-axis. The point where the two lines meet at “0” is the origin.
