This is quite simple, first, you must find the area of each shape, since the form of the prism is currently 2D.
Formula for (Area of Rectangle)= length x width
Formula for (Area of Triangle)= 1/2 base x height
Now, we have the formulas. Let’s get started!
(Identification) There are 3 rectangles and 2 triangles. 2 rectangles are of the same size and 2 triangles are of the same size.
Triangles~ the base is 6 and the height is 4.
1/2 (6 x 4) = 12
However, there’s two triangles. (of the same size)
12 x 2 = 24
Rectangles 1 and 2~ the length is 5 and the width is 7
5 x 7 = 35
However, there’s two rectangles. (of the same size)
35 x 2 = 70
Rectangle 3~ the length is 6 and the width is 7
6 x 7 = 42
There’s only one of these.
Now we add all the areas of the shapes together!
24 + 70 + 42 = 136
The surface area is 136.
To find the total revenue for any object, you simply multiply the price of the object by the number of units sold.
In this case, the revenue for helments would be 3*14, and the revenue for bicycles would be 125*b.
Knowing that total revenue was 917, we can form an equation:
125b + 3*14 = 917
125b + 42 = 917
Subtract both sides by 42:
125b = 875
b = 7
Sawyer sold 7 bicycles
3=6 ; 6+8=180
(2x-5)+(x+5)=180
X=60
6=115, 8=65
Hope that answer can help you!
