The area of the rectangular is expressed in the formula A = l*w where l is the length and w is the width. from the first satement, l = 2 + w; then A = (2+w)*w = 2w + w^2. If A is equal to 168, then w should be equal to 12 feet and l is equal to 14 feet. Hence the width due to the border limits is 12- 2*2 equal to 8 feet

malfutka [58]

What you do is add up all the values, then divide by the number of values.
$\frac{1.90+7.99+4.33+5.21}{4}=\frac{19.43}{4}=4.8575$
The average of the data is 4.8575.
