Answer:
(4000 in^2) * (1 ft/12 in)^2 = 27 7/9 ft^2
Step-by-step explanation:
4,000 Square Inches =
27.777778 Square Feet
Answer:
1/4
Step-by-step explanation:
slope=y2-y1/x2-x1
x1= -10
y1 = 4
x2 = -2
y2 = 6
putting values in formula
6-4/-2-(-10)
2/10-2
2/8
1/4
To find the area of a triangle, the formula is

=A
Since you have the area and the base you can replace the variables and place the numbers into its place.
17.5 =

From here you need to solve for h by first multiplying the (1/2) and 7 which would equal 7/2 or 3.5
Then you would have
17.5 = 3.5(h)
Now you divide both sides by 3.5 which would make h equal to
h=5
Double check and do

which would equal to

All of that equals to 17.5, which is the correct answer so the height is 5m.
It would be helpful to draw the figures, you will see that for ABCD there 2 lacking side lengths which are AB and CD. For EFGH, there is one lacking side length which is EH. We use the ratios of the corresponding sides to determine side EH. We do as follows:
FG / BC = EH / AD
10 / 8 = EH / 12
EH = 15
Therefore, the perimeter would be:
15+10+5+15 = 45 units
