Answer:
16 children
Step-by-step explanation:
80% of 20 children comes out to 16 children who are of age 5.
If desired, rewrite "80%" as "0.80" and use that 0.80 as the multiplier of 20:
0.80(20 children) = 16 children.
Let the width of the rectangle be x
Then length =x-4
Area=x(x-4)=140
x²-4x=140
x²-4x-140=0
x²-14x+10x-140=0
x(x-14)+10(x-14)=0
(x-14)(x+10)=0
Therefore,length=14 cm and width=10 cm
