Answer:
a) -6
b) 9
c) 27
Step-by-step explanation:

BC is 6.08, use distance formula to calculate
height is BE and also 6.08
AD is 18.25
A= h((a+b)/2)
=6.08(6.08+18.25)/2)
= 73.96 units^2 is the area
Answer:
the answer is 12 inches
every inche equals 15 feet from 30/2 then divide it by the total 180/15 which equals 12
Width = 4ft
Length = 6ft
<u>Explanation:
</u>
Let length = l ,
So, width = 2l-8
Perimeter of rectangle = 2x(length + width)
According to the question,

Hence,
Width = 4ft
Length = 6ft
