Simplified answer is 4+8i
Answer:.0.045
Step-by-step explanation:9x5 =45 then count how many #’s behind both decimal points .09 and .5 would be three so your answer should have 3 numbers behind decimal= 0.045
This is called a literal equation where in this case you solve for w in terms of l and p.
P=2l+2w
Move "2l" over to the other side.
P-2l=2w
Divide by 2 on both sides.
p/2-l=w
Rearrange.
w=p/2-l
answer: p/2-l
Answer:
Answer: 84 meters squared. (i.e. 84m^2).
Step-by-step explanation:
Area of the path = total area of path and plot - plot area only
First, let’s find the area of the plot:
20m x 20m = 400m^2
The path is 1m wide and runs all the way around, so, it describes an ‘outer square’ of 22m x 22m (2 x 1m larger because there are 1m of the path on each side).
The area of this ‘outer square’ is equivalent to the ‘total area of path and plot’
22m x 22m = 484m^2
So:
Area of the path = total area of path and plot - plot area only
= 484 - 400 = 84m^2
