Question

1 the perimeter of rectangle is 17 cm. if its width is this is mixed fraction 3 3 by 4 centimetre find its length
2 solve a. x-2=17
b. x/3+1=7/15
c. x-3/7=-14/3
d. x/3+3/2=5/2
e. t+3/4=27/4

Answer 1

Perimeter of rectangle = 2 (l + b)
It is given that

b = 3  3/4
   = 15/4 Cm

And Perimeter = 17 Cm
Thus
17 = 2 (l + 15/4)
  l + 15/4 = 17/2
  l = 17/2 - 15/4
  l = 21/4 Cm
