length of the cardboard =-10/7
breadth of the cardboard =5/4
area=l×b
=-10/7 × 5/4
=-50/28
=-10/14
=-5/7
no. of cards made=5
area of each card = -5/7÷5/1
=-5/7×1/5
=-1/7
area of three cards = 3×-1/7
=-3/7
breadth of the cardboard =5/4
area=l×b
=-10/7 × 5/4
=-50/28
=-10/14
=-5/7
no. of cards made=5
area of each card = -5/7÷5/1
=-5/7×1/5
=-1/7
area of three cards = 3×-1/7
=-3/7
How is -50/28=-10/14?
how can length be negative
