The answer is 95%
This is something you should memorize. Specifically it is from the Empirical Rule (or 68-95-99.7 rule) which gives rough approximations of areas under the curve.
9+(5+3) is going to be 17
Answer: 6928
----------------------------------------------------------
Explanation:
We have two areas we need to find: The area of the trapezoid and the area of the rectangle. Let's call these areas A1 and A2.
Area of Trapezoid = (height)*(base1+base2)/2
A1 = h*(b1+b2)/2
A1 = 80*(150+100)/2
A1 = 80*250/2
A1 = 20000
A1 = 10000
Area of Rectangle = (length)*(width)
A2 = L*W
A2 = 48*64
A2 = 3072
Subtract the two areas (A1-A2) to get the difference D
D = A1 - A2
D = 10000 - 3072
D = 6928
This difference D is exactly equal to the shaded area.
The answer is 6. 480 divided by 80 gives you the answer 6.
Answer:
27 units²
Step-by-step explanation:
Cut the figure into a 8 by 3 rectangle and triangle.
The area of the rectangle is 8*3 or 24
The area of the triangle is 3 using the formula 1/2bh where the base and height are 3.
Adding those 2 areas together 24+3 will equal 27
