18. The length of a rectangle is 5 cm more
than its breadth. If its area is 60 sqcm then
its equation form is
एक लंबचौके की लंबाई 5cm उसकी चौडाई से
ज्यादा है। अगर इसका क्षेत्रफल 60 sqcm है तो
इसका समीकरण
(a)x+(x+5)-60=0
(b) x+(x+5)+60%D0
(c) x(x+5)+ 60=0
(d) x(x+5)-60=0

Answer:
Let the shorter side of triangle =x cm
The other side of the triangle =(x+5)cm
The area of reactangle
(x+5)(x)=150
⇒ x
2
+5x−150=0
⇒ (x+15)(x−10)=0
⇒ either x=−15 or x=+10
Since the side cannot be negative
Therefore the value of c=−15 is negligible
When x=10cm, then the other side
