A square has an area of 16,900 square feet what is the length of one side of the square?

Paha777 [63]

Let $a$ be the length of the square, then the area is $a^2$ . Hence, the side is the positive root of the area, which is $a=\sqrt{16900}=\boxed{130 feet}$

Nathan is building a toolshed with a rectangular floor. The area of a rectangle is given by the formula l⋅w, where l represents

Pachacha [2.7K]

Answer:

Here, l is the length of the rectangle and w is the width of the rectangle

To Compare the values, you must calculate each given situation.

Area of a rectangle is equal to length times width.

i.e, $A = l \times w$

(A)

if l = 8 units and w= 6 units,

then;

$A = l \times w$ = $8 \times 6 = 48 unit^2$

(B)

if l =7 units and w = 7 units

$A = l \times w$ = $7 \times 7 = 49 unit^2$

Therefore, the Part B would yield a larger area.

If l -7 units and w = 7 units , the area of larger floor is 49 square units.
