Answer 2

Let suppose Length(L)= 2 1/4 units which is 9/4 in proper fraction and 2.25 in decimal
let suppose Width(W)= 7/10 units which is 0.7 in decimal
Perimeter(P)=?
Now, we should use the formula P = 2(L+B)
                                                       = 2(2.25+0.7)
                                                       = 2(2.95)
                                                       = 5.9
so, the perimeter = 5.9 units.
