Question

the length of a rectangular plot is twice its breadth. if the perimeter of the plot is 522 metre, find the area of the plot​

Answer 1

Step-by-step explanation:

Area =528m

2

Let Breadth be b

Then length l=2b+1

So (b)(2b+1)=528

⇒2b

2

+b−528=0

⇒2b

2

−32b+33b−528=0

⇒2b(b−16)+33(b−16)=0

⇒(2b+33)(b−16)=0

So b=16

l=33
