Given:
Area = 21 in²
length = 6 in.
width = ?
The area of a rectangle is computed by multiplying its length by its width.
A = l * w
21 in² = 6 in * w
To find width, divide the area by its length.
21in²/6in = w
3.5 in. = w.
The width is 3.5 inches.
to check:
Area = Length * Width
21 in² = 6 in x 3.5 in
21 in² = 21 in²
Cross multiply.
5.4x=9*25.8
5.4x=232.2 Divide both sides by 5.4
x=43
8 children because
11 3/7 is equal to 83/14
If each child receives 10/14
83/10
= 8.3
There can't be .3 of a child so round it and you get 8!
Hope this helps!
