1. The area of a rectangular garden is 8064 m2. If the width of the garden is 84 m, what is its length?

Length of the garden:

2. The perimeter of a rectangular window is 288 cm.
If the length of the window is 87 cm, what is its width?

Width of the window:

Length of the garden: 96m

Width of the window: 56cm

Step-by-step explanation:

L=96m

W=57cm

Step-by-step explanation:

General formula of the area of rectangle would be

Length * Width = Area

Length * 84 = 8064

By dividing both sides of equation by 84

Length = 8064/84 = 96m

General formula of the perimeter of rectangle would be

Perimeter = 2(Length + Width)

288 = 2(87 + Width)

By dividing both sides of equation by 2

144=87+Width

By substracting 87 from both sides of equation

144-87=Width

Width = 57cm

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
