a).  Area = (length) (width)

               = (60 ft) (√18 ft)

               =     (60 √18)  ft²

               =     60 √(9 · 2)   ft²

               =     60 (3) √2      ft²
 
               =   180 √2           ft²     (about  254.6 ft²)


b).  Volume  =  (length) (width) (height)

                    =  (60 ft) (√18   ft) (√10   ft)

                    =        60 √(180)         ft³

                    =        60  √(4 · 9 · 5)          ft³

                    =        60 (2) (3) √5             ft³    

                    =       360 √5         ft³        (about  805 ft³)

A square has a perimeter of 28 feet what is its area
Westkost [7]
Given:
square shape
Perimeter 28 feet
Find its area

A square has 4 equal sides, so perimeter is 4a

Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a

One side of the the square is 7 ft.

Area of a square is the measure of one side raised to the power of 2.

A = a²
A = (7 ft)²
A = 49 ft²
