Question

Length of a rectangle is 6 m less than twice its breadth. The perimeter of the rectangle is 240 m.

Answer 1

Answer:

Step-by-step explanation:

Let breadth of rectangle be x

Then length is (2x-6)

Perimeter of the rectangle is 2(l+b)=240

By putting values

2(2x-6+x)=240

2(3x-6)=240

6x-12=240

6x=240+12

6x=252

X=252/6

X=42

So, breadth of rectangle is 42,

And length =2x-6

=84-6

=78

So,length and breadth is 42 and 78 respectively

Answer 2

length of a rectangle=6m
breadth of a rectangle =?
perimeter of rectangle =240m
240m=6m
240m÷6m
40m
less than twice a breadth =40÷2
=20
the breadth is 20m
