Question

in a rectangle of perimeter one metre,one side is five centimetres longer than the other. What are the lengths of the sides?​

Answer 1

Answer:

Answer. And one side is 5cm long than the other. first side =22.5cm.

Answer 2

Let the shorter side of triangle =x cm

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cm

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2 +5x−150=0

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2 +5x−150=0⇒ (x+15)(x−10)=0

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2 +5x−150=0⇒ (x+15)(x−10)=0⇒ either x=−15 or x=+10

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2 +5x−150=0⇒ (x+15)(x−10)=0⇒ either x=−15 or x=+10Since the side cannot be negative

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2 +5x−150=0⇒ (x+15)(x−10)=0⇒ either x=−15 or x=+10Since the side cannot be negativeTherefore the value of c=−15 is negligible

Let the shorter side of triangle =x cmThe other side of the triangle =(x+5)cmThe area of reactangle(x+5)(x)=150⇒ x 2 +5x−150=0⇒ (x+15)(x−10)=0⇒ either x=−15 or x=+10Since the side cannot be negativeTherefore the value of c=−15 is negligibleWhen x=10cm, then the other side =10+5=15cm
