Step-by-step explanation:
A spreadsheet or graphing calculator can do this for you.
Answer:
Its A
Step-by-step explanation:
<span>let the width of the strip x in meters
we need to find the value of x
Dimensions of the new lawn are given as
</span>(7+x) by (5+x)
Area of the lawn is given as
6.25m^2
<span>
(7+x)(5+x) = 6.25
</span><span>35 + 12x + x^2 = 6.25
x^2 + 12x+28.75 = 0
In the above equation the values are given as
a = 1, b=12, c=28.75
</span>put these values in quadratic equation and you will get the answer.<span />
Answer:
12 because 1:2 so times 6 we get 6:12
