Question

A rectangular living room has a perimeter of 22 meters and an area of 30 square meters.
What are the dimensions of the living room

Answer 1

Answer:

6m x 5m

Step-by-step explanation:

P= 2(l+w)

there's probably a proper formula for this but i just looked at the factors of 30 and then added them to see which ones equaled half of 22 (that's 11)

factors of 30: 1, 30/ 2, 15/ 3, 10,/ 5,6

1+30/ 2+15/ 3+10 do NOT equal 11.

However, 5+6 = 11.

Check:

P= 2(l+w)

2(6+5)=P

30=P

30=30
