Question

the city park shown at the right has an area of 6889 square meters. the parks length along front street is 83 meters. find the length of the park along second avenue

Answer 1

To find second side of park we can use formula for area of rectangle.
ITs
A=a*b
Where A is area and a ,b area sides of it/
We can convert our area
A=a*b  /:a      divide both sides by a (its no matter which side we assume to be 83)
$\frac{A}{b} =a$
Now we can substitute to our formula.
$a= \frac{6889}{83}=6889:83=83$ - its second side and its our answer.
