A square garden has a diagonal of 34 ft. Colton wants to put a fence around the entire garden. How much fencing will he need? Round to the nearest foot.

Answers

Answer 1
Answer: ok
pythagorean theorem
a and b are legs, c is hypotonuse (diagonal in this problem)
in square, legs are equal
a=b

a^2+b^2=c^2

diagonal is 34
a=b
a^2+a^2=34^2
2a^2=1156
divide both sides by 2
a^2=578
a=17√2

perimiter is 4 time 1 side for square
p=4 times 17√2
P=68√17 feet

aprox 96.1665 feet
Answer 2
Answer: Let s be the length of a side. 

By the Pythagorean Theorem (or knowledge of 45-45-90 triangles) we can find the length of a side from the hypotenuse. 
s² + s² = 34² 
2s² = 34² 
2s² = 1156 
s² = 578 

s = √578 
s ≈ 24.04 

There are 4 sides to the square: 
P = 4s 
P ≈ 96.16 

Answer: 
About 96 feet

How can you use the Distributive property to solve multistep equations​

Answers

Solve by clearing the fractions in the equation first.
Multiply both sides of the equation by 4, the common denominator of the fractional coefficients. Use the distributive property to expand the expressions on both sides. Add 3x to both sides to move the variable terms to only one side.
