Room plan perimeter

Róbert's children's room has a rectangular floor plan, and the carpet that covers the entire floor has an area of 12 m2. One side has a dimension of 2.5 m. The plan of this room is drawn on a scale of 1:100. What is the perimeter of the rectangle representing Robert's room on this plan?

Final Answer:

x =  14.6 cm

Step-by-step explanation:

S=12 m2 a=2.5 m  S = ab b=S/a=12/2.5=524=4.8 m  o=2 (a+b)=2 (2.5+4.8)=573=14.6 m M=100  o2=o cm=o 100  cm=14.6 100  cm=1460 cm x=o2/M=1460/100=14.6 cm
