Answer:
Step-by-step explanation:
Area of square= l×l
Area of square= 6mm × 6mn
Area if square = 36 mm²
Area of triangle 1= ½b ×h
Area of triangle 1= ½ (6mm)(8mm)
Area of triangle 1 = 24 mm²
Area of triangle 2 is the same as area of traingle 1 because they have the same base and hight
: . area of triangles is 48mm²
Area of the figure= Area of square + Area of triangles
A of figure = 36+48
A of figure = 84 mm²
Option 2
Use trapezium formula
Area of trapezium= (a+b)/2 * h
a=6 mm (base)
b=8+6=14 mm (Base)
h= 6mm (height)
Therefore the area of triangle= 24mm² as calculated in option 1
Area of the figure= Area of trapezium +Area of triangle
Area of figure = 60+24
= 84 mm²
Answer:
Step-by-step explanation:
You need to analize the information given in the exercise.
In this case you know that the List price is:
And, based on the data given, you also know that the Trade discount is:
Then, the first step you need to apply is to multiply the List price by the Trade discount, as you can observe below:
Now it is important to remember that, by definition, the Net cost can be found by subtracting the List price (which in this case is $74.13) and the product of the List price and the Trade discount (which in this case is $24.71).
Then, through this procedure, you get the following Net cost:
