Answer:

<u><em>B:  6 root 2</em></u>

Step-by-step explanation:

this is a right angled triangle having two sides perpendicular and base equal to 6cm

Using the Pythagorean theorem

(Hypotenuse)² = (perpendicular)² + (base)²

c²= (6)²+ (6)²= 36+36

c= √72= √36*2= 6√2= 6 root 2

Mr. Drew wants to build a square sandbox for his children. The area of the sandbox will be 70 ft squared . To the nearest​ tenth
ziro4ka [17]

Answer:

Mr. Drew needs 167.3 ft of wood

Step-by-step explanation:

we know that

The area of a square is

A=b^{2}

where

b is the length side of the square

we have

A=70\ ft^2

substitute in the formula and solve for b

70=b^{2}

square root both sides

b=\sqrt{70}\ ft

To determine the total length of wood , calculate the perimeter of the sandbox

The perimeter of the sandbox is equal to the perimeter of 5 squares

so

P=5(4b)

substitute the value of b

P=5(4(\sqrt{70}))=167.3\ ft

therefore

Mr. Drew needs 167.3 ft of wood
