Question

The perimeter of a rectangle is 34 metre.The width is 4 metre.what would the length be

Answer 1

Answer:

Let the length be x, and breadth be y.

Therefore, 2(x+y)=34

x+y=17

y=17−x

Hence, Area =x(17−x) =60

17x−x

=60

x

−17x+60=0

x

−12x−5x+60=0

x(x−12)−5(x−12)=0

(x−5)(x−12)=0

Hence the sides are 12 m and 5 m
