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

$P=5(4b)$

substitute the value of b

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

therefore

Mr. Drew needs 167.3 ft of wood

What is the thoerema of Pitagora ?

stellarik [79]

The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found. Another corollary of the theorem is that in any right triangle, the hypotenuse is greater than any one of the other sides, but less than their sum.

hope this helped:)
