Question

Write all the combination of length and breadth of rectangle whose perimeter can be 20 metres

Answer 1

Answer:

Step-by-step explanation:

2(l + b) = 20m

l + b = 20/2

l + b = 10m

1m and 9m

2m and 8m

3m and 7m

4m and 6m

5m and 5m

Answer 2

Write all the combination of length and breadth of rectangle whose perimeter can be 20 metres

L = 1 m and B = 9 m

L = 2 m and B = 8 m

L =  3 m and B = 7 m

L = 4 m and B = 6 m

L = 5 m and B = 5m

Solution:

Given that,

Perimeter of rectangle = 20 meter

We know,

Perimeter of rectangle = 2(L + B)

Where, "L" is length and "B" is breadth of rectangle

Therefore,

20 = 2(L + B)

L + B = 10

Possible combinations are:

L = 1 m and B = 9 m

L = 2 m and B = 8 m

L =  3 m and B = 7 m

L = 4 m and B = 6 m

L = 5 m and B = 5m
