Answer 2

Answer:

15.8m

Step-by-step explanation:

perimeter of a rectangle is given by:

p = 2(L + b) • where L represents the length

• where b represents the breadth

in this case:

L = 7m

b = 9dm

but 1dm = 0.1m

therefore 9dm = (9dm × 0.1m) / (1dm)

giving us: 0.9m

thus b = 0.9m

so,

p = 2( 7m + 0.9m) = 15.8m

its perimeter is 15.8m
