The wall

The wall in the bathroom has dimensions of 2.8 m and 2.6 m. Suppose we would like to cover this wall to a height of 1.6 m. How many square meters of tiles do we need to buy?

Correct answer:

S =  24.56 m2

Step-by-step explanation:

a=2.8 m b=2.6 m c=1.6 m o=2 (a+b)=2 (2.8+2.6)=554=10.8 m S=a b+c o=2.8 2.6+1.6 10.8=24.56 m2
