Answer 1

Answer:

45m answer....................

Answer 2

Step-by-step explanation:

according to the question ,

the length of a rectangle is 10 m more than it's breadth.

the perimeter is 80 m

so, let the breadth of rectangle is x

then the length is 10+x.

now, 2(l+b) =perimeter

2 {x+(10+x)} =80

or 2{ x+10+x}=80

or 2{ 2x+10}=80

or 4x+20 =80

or 4x=60

or x=60÷4

or x=15

so,we have got the breadth=15m

Now, length= breadth +10

=15+10

=25m

answer: the length is 25m and breadth is 15m
