Answer 1

Answer:

The length of a rectangle is 5 cm more than its breadth. If the length is decreased by 3 cm and breadth is decreased by 2 cm, then area of the new rectangle is same as the area of the original rectangle. Find the dimensions of the original rectangle.

Step-by-step explanation:

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 =10+5=15cm
