Answer:
114m^2
Step-by-step explanation:
At first it looks like you can split this into 3 rectangles, but the easier way is to subtract the area that is cut out from the larger rectangle. In this image, we have an outer rectangle that measures 12m x 14m. In the middle, there is a 9x6 rectangular hole. Subtract the area of the hole from the total area of the rectangle.
Total area = 12 * 14 = 168
Area of hole = 6 * 9 = 54
Area left = Total area - Area of hole
= 168 - 54
= 114m^2
Answer:
33π
Step-by-step explanation:
The circumference of a circle as 2πr, meaning that with a radius of 16.5m, the circumference would be 2*16.5*π, or 33π.

Answer:

Step-by-step explanation:
The equation of the line you will find should be in the form y =mx+c , where m is the gradient and c is the y intercept.
The gradient of a line that is perpendicular to a line [of a known gradient] is the negative reciprocal of the gradient of the first. i.e. if a is the known gradient and the perpendicular gradient is b, ab = -1. Therefore the -3b=-1 and b= 1/3
you can now write y = mx +c as y = 1/3x +c
As you have been given a coordinate, you can input these values into y= 1/3x + c
-12 = 1/3(6) +c
-12 - 2 = c
c = -14
hence the equation of the line is y= 1/3x -14
