Question

The diagonal of a rectangular field is 28 meters more than the shorter side. Find the lengths of the sides of the rectangular field.​

Answer 1

HOPE THIS HELP YOU

Let the shorter side =x m

diagonal of the rectangle =x+16 m

Longer side =x+14 m

∴(AB)

∴(x+14)

+28x−32x+196−256=0

⇒x

−4x+60=0

⇒x

−10x+6x−60=0

⇒x(x−10)+6(x−10)=0

⇒(x−10)(x+6)=0

Hence, x=10 or −6

x=−6 is not admissible

So, x=10

Breadth of rectangle =10 m

Length of rectangle =10+14=24 m
