I would go with the answer D
Answer:
Length in feet is equal to
, where P is the perimeter
Step-by-step explanation:
Let the width (W) of the yard be "X"

Then the length(L) of the yard will be


The perimeter of the yard will be equal to the sum of twice the length and width of the yard
Thus,

Substituting the given values in above equation, we get -

Thus, width in terms of perimeter is equal to

Length in feet is equal to 
Answer:
90 m
Step-by-step explanation:
The piece on the right side fits perfectly in the left side so you can move the triangle to the left in order to make a square. After that, you can do 10 times 9 because 5+4=9 to get 90m as the area.
Answer:
x = 9
Step-by-step explanation:
divide both sides of the equation by 4 to isolate the x variable according to algerba. Hope it helps!
Isocoleese means 2 angles are same, normally the base angles
so since it says they measure 42
rememeber that all angles in traingle add to 180
so base angles+vertex angle=180
base angles aer both 42 so
2 times 42+vertex angle=180
42 times 2=84
so
if veretx angle=z then
84+z=180
answer is B
