For a rectangle, the perimeter can be calculated as P=2l+2w. Assuming the length is horizontal and the width is vertical, the span between the x coordinates will give the length, while the span between the y coordinates will determine the width. Once these measurements are obtained, you can apply them to the perimeter formula. |7 -(-7)| = 14 gives l = 14, |5-(-2)| = 7 gives w=7. Therefore, P=2(14)+2(7), which results in P= 28+14, thus, P= 42.
The equation of the line through the point (5,4) with a slope of 6/5 is y = 6/5x - 2. This is determined using the linear equation format y = mx + b. By substituting in the values, you can simplify to find the y-intercept.
Answer:
13 Millilitres.
Step-by-step explanation:
Yoku applies 2ml to cover 
of his skin.
He seeks to find out how many millilitres he needs to cover 
of his body.
With 2ml, Yoku covers of his skin
He will use 
of sunscreen for covering 
of his skin.
Thus:
For covering of his body, he will require:
he would need 13 Millilitres.
