const2013 [10]

If the width of peter's garden is 32 yards, the ratio of the areas is 47: 32

<h3>Area of a rectangle.</h3>

area of rectangle = lw

where

  • l = length
  • w = width

Therefore,

Peter rectangular garden

  • l = 15 + x

Jorge is planting a square garden. The sides of Jorge's garden are equal to the width of Peter's garden.

Therefore,

  • x = side of Jorge garden

The ratios are as follows;

(15 + x)x : x²

Therefore, if the width of peter's garden is 32 yards, the ratio of the areas is as follows:

(15 + 32)32 : 32²

1504: 1024

752: 512

376: 256

94:64

47: 32

The variables xx and yy vary directly. use the values to find the constant of proportionality, kk. then write an equation that r
Sergeu [11.5K]
Direct variation means that changes in x will result to changes in y. If x increase, y also increases and vice versa.

y = kx
k = y / x

y = 45 ; x = 40

k = 45/40 
k = 1.125

y = 1.125x 

y will increase by 1.125 interval of x.
