8 4/8 - 2 2/8 = 6 2/8in or 6.25in
Answer: 84 ft^2
Step-by-step explanation:
The whole prism can be divided into 5 surfaces.
Two triangles and 3 rectangles.
Find the area of each of the 5 shapes and add them together.
The triangle has a base of 4 and a height of 3.
Area of triangle 1: A= 4*3 * 1/2
A = 6
Area of triangle 2: A = 4*3 * 1/2
A = 6
Area of rectangle 1 : A= 4*6
A = 24
Area of rectangle 2; A = 3*6
A = 18
Area of rectangle 3: A= 5 *6
A = 30
Now add the areas together
6 + 6 + 24 + 18 + 30 + = 84 ft^2
Its a trapezoid of course! :)
The answer is 72
you first start by doing whats in the parenthesis: 72-63. that equals 9. then do the brackets [4(9)/3] do this from left to right 4x9=36. 36/3= 12 last do 6x12 that equals 72 which is the most simplified version
