Answer 1

Answer:

length = 25 meters

breadth = 15 meters

Step-by-step explanation:

Let the breadth of the rectangle be 'm'

so, according to the given information, the length = 10 + m

Now, perimeter if any polygon is the sum of the length of its sides.

so, perimeter of a rectangle = 2*length + 2*breadth

=> 80 = 2(10+m) + 2m

=> 4m + 20 = 80

=> m = 15

so, length = 10 + m = 10 + 15 = 25 meters.

and breadth = m = 15 meters.

Answer 2

Answer:

Given that length of rectangle is 10m more than its breadth.

therefore, breadth ( b) = b

length ( l ) = 10 + b

perimeter = 80m

Perimeter of rectangle = 2 ( length + breadth )

80 = 2 ( 10 + b + b )

80 = 2 ( 10 + 2b )

2 ( 10 + 2b ) = 80

10 + 2b = 80/2

10 + 2b = 40

2b = 40 - 10

2b = 30

b = 15

therefore, breadth ( b ) = 15m

length ( l ) = 10 + 15 = 25m
