The perimeter of a rectangular plot is 62 m and its area is 228 sq metres. Find the dimensions of the plot.

Text Solution

Verified by Experts

The correct Answer is:
length = 19 m, breadth = 12 m
`2(l+b)=62impliesl+b=31." Let "b=x" m. Then,"l=(31-x)m`
`:." "(31-x)x=228impliesx^(2)-31x+228=0impliesx^(2)-19x-12x+228=0.`
