Answer:
Area of rectangle = 225/2 or 112.5
Step-by-step explanation:
Given,
Consider a rectangle ABCD.
Let AC be a diagonal of rectangle of length = 15
In triangle ABC.
Sin 45° =height/hypotenuse {SinФ = height / hypotenuse}
Here, hypotenuse = diagonal of rectangle ( i.e AC = 15)
And height is AB
Therefore, sin 45° = AB/AC
or sin 45° = AB / 15
or 1/√2 = AB /15
AB = 15/√2
Similarly we can find Base (i.e BC) using cosine.
Cos 45° = Base/Hypotenuse
Cos 45° = BC / AC
or 1/√2 = BC/15
BC = 15/√2
Hence we got length of rectangle , AB= 15/√2
And width of rectangle , BC = 15/√2
Therefore, area of rectangle = Length × Width
Area of rectangle = 15/√2 × 15/√2 = 225/2
Hence, area of rectangle = 225/2 = 112.5
Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Part 5) 
Step-by-step explanation:
Part 1) Write as a percent 0.00675
we know that
To write a number as a percent, multiply the number by 100
so
Part 2) Write as a percent 4 3/4
Convert mixed number to an improper fraction
we know that
To write a fraction as a percent, multiply the fraction by 100
Part 3) Write as a percent 2/25
we know that
To write a fraction as a percent, multiply the fraction by 100
Part 4) write as a fraction 335%
we know that
Simplify
Divide by 5 both numerator and denominator
Part 5) Write as a decimal 265%
we know that
The answer is 12.
The exact answer is 11.74734012..... this question is basically asking you to round the exact answer.
