The length and breadth of a rectangular playground are 110m and 90m.
(a) Ratio of length to perimeter = 11 : 40
(b) Ratio of breath to perimeter = 9 : 40
<u>Solution:
</u>
Given that length of play ground = 110 m
And breadth of playground = 90 m
Need to determine ration of (a) length to perimeter and (b) perimeter to breadth
Lets first calculate perimeter of rectangular playground
<em>Perimeter of Rectangle = 2(length + breadth ) </em>
=> Perimeter of Rectangular playground = 2(110 + 90) = 400 square meter
Now substituting values in ratio we get,
(a) Ratio of length to perimeter = 110 : 400 = 11 : 40
(b) Ratio of breath to perimeter = 90 : 400 = 9 : 40
Answer:
I think you mean area, but acres
First, subtract 30x from each side to get:
-60 = -10x
Then, divide each side by -10 to get:
x = 6
Now, plug back in to check your answer:
30(6) - 60 = 20(6)
180 - 60 = 120
120 = 120
Hope this helps!! :)
Answer: To find the inverse, interchange the variables and solve for y.
