Answer:
Step-by-step explanation:
You want the area and perimeter of a floor that is 12.5 m by 1300 cm.
There are 100 cm in 1 m, so 1300 cm = 13 m.
The area is the product of the dimensions:
A = LW = (12.5 m)(13 m) = 162.5 m²
The area of the floor is 162.5 square meters.
The perimeter is the sum of the edge lengths. Each edge is the same length as its opposite.
P = 2(L +W)
P = 2(12.5 m + 13 m) = 2(25.5 m) = 51 m
The perimeter of the floor is 51 meters.
