Area = 8,100 square feet
area of a square = a²
8,100 square feet = a²
√8,100 square feet = √a²
90 feet = a
total length each row of bookshelf is 4/5 of the length of the storage space.
90 feet * 4/5 = (90*4)/5 = 360/5 = 72 feet.
Area = (72 ft)²
Area = 5,184 square feet.
For this case we have the following point:
i - 2
The first thing you should remember is that in a complex number plane:
The vertical axis represents the imaginary part.
The horizontal axis represents the real part.
Answer:
See attached image.
Answer:
Perimeter = 54.6 cm
Area = 173 cm²
Step-by-step explanation:
sin 30 = x/20
x = 10
cos 30 = y /20
y = 17.3
perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm
area = 10 * 17.3 = 173 cm²
Well if $1=82 than $100 (which is 100 times 1) would equal 82·100=8,200
$1,000·82=82,000
$10,000·82=820,000 :) hope this helps!
