Question

5. The area of a rectangle is 24 cm². If the length of the rectangle is 8 cm, find its breadth​

Answer 1

Answer:

Let the breadth of the given rectangle be x cm.

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cm

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2 +8x−240=0⇒x

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2 +8x−240=0⇒x 2

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2 +8x−240=0⇒x 2 +20x−12x−240=0⇒(x+20)(x−12)=0

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2 +8x−240=0⇒x 2 +20x−12x−240=0⇒(x+20)(x−12)=0⇒x=12orx=−20

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2 +8x−240=0⇒x 2 +20x−12x−240=0⇒(x+20)(x−12)=0⇒x=12orx=−20But x cannot be negative, So, x=12

Let the breadth of the given rectangle be x cm. Then, length =(x+8) cmNow area =240cm 2 ⇒length×breadth=240⇒(x+8)x=240⇒x 2 +8x−240=0⇒x 2 +20x−12x−240=0⇒(x+20)(x−12)=0⇒x=12orx=−20But x cannot be negative, So, x=12Hence, length =x+8=12+8=20cm and breadth =12cm

Answer 2

Area of rectangle = length * breadth

=24*8=192

=192
