Question

The perimeter of a rectangle is 22 cm and the length of each side is a natural number. How many different areas in square centimetres can the rectangle have?

Answer 1

Answer:

Step-by-step explanation:

7 and 24

Step-by-step explanation:

perimeter=2(1+b)

area =lxb

perimeter:

22=2(l+b)

11=l+b

before we need to find two numbers whose sum is 11 and whose product is 28

so the numbers are:

1,10

2,9

3,8

4,7

5,6

so as per the requirement there is only one pair which can satisfy the requirement which is 7 and 4
