Answer:
11 units
Step-by-step explanation:
The height of a trapezoid is the distance between the parallel bases.
__
Here, one base lies on the horizontal line y=5, and the other lies on the horizontal line y = -6. The distance between them is ...
5 -(-6) = 5 +6 = 11
You can also find this distance by counting the grid squares between the two parallel lines.
The height of the trapezoid is 11 units.
_____
<em>Additional comment</em>
The base lengths are ...
AB = 2 -(-5) = 7
CD = 8 -(-7) = 15
The area is 1/2(b1 +b2)h = (1/2)(7 +15)(11) = 121 square units.

Step-by-step explanation:
<u>Length Of Semicircles
</u>
The length of a circle or radius r is
A semicircle has half this length:
The radius of the flowerbed is 2.5 m, thus the length of the edging material needed to border the lawn design is
Answer:
Length=15 cm
Width=13 cm
Step-by-step explanation:
-Let x be the width dimension, the length will be (x-2)
-The area of a rectangle is given by the formula;
#We substitute the length and width values and equate to the given area:
#Rewrite as a quadratic and solve for x:
Since dimensions are always positve, the x value is 15
x=15
x=13
Hence, the dimensions of the rectangle are length=15 cm and width=13 cm
The answer would be 9(8b+5)
this is how you do it...
1. find the GCF of both numbers in this one the GCF would be 9
now, what do you multiply 9 by to get 72... 8, so 8 would go into the parenthesis and because there is a variable there which is 'b' the 8 would become '8b' now what do you multiply 9 with to get 45? '5' so you would add 5 into the parenthesis and that would be your answer!
Hope this helped! :D
The midpoint is 15 hope i helped
