Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area.

Alekssandra [29.7K]

Answer:

Area of window = 3 ft²

Area to be painted = 45 ft²

Explanation:

To get the area to be painted, we will start by getting the area of the whole wall (including the window), then subtract from it the area of the window

1- getting area of whole wall:

From the figure, we can note that the length and width of the wall are given as 6 ft and 8 ft

Area of whole wall = length * width

Area of whole wall = 6 * 8 = 48 ft²

2- getting area of window:

Again, from the figure, we can note that the length and width of the window are 2 ft and 18 in (which is equivalent to 1.5 ft)

Area of window = length * width

Area of window = 2 * 1.5 = 3 ft²

3- getting area to be painted:

Area to be painted = area of whole wall - area of window

Area to be painted = 48 - 3 = 45 ft²

Hope this helps :)

The point C at a coordinate of (-3, 4) is the center of dilation of shapes WXYZ to W'X'Y'Z'

<h3>How to determine the center of dilation?</h3>

The coordinates are given as:

W = (-4, 3) X = (-2, 3) Y = (-4, 1) Z = (-2, 1)
W' = (-6, 1) X' = (0, 1) Y' = (-6, -5) Z' = (0, -6)
A = (-5, 4) B = (-3, 6) C = (-3, 4) D = (-1, 4)

Next, we plot the points on a coordinate plane

From the plane (see attachment), we can see that the point C at a coordinate of (-3, 4) is at the center of both shapes, and it is 1 unit from WXYZ and 3 units from W'X'Y'Z'.

Hence, the point C is the center of dilation
