The perimeter represents the amount of wood needed and the area represents the amount of class needed.  

so 2*(2/3) +  2(2) = 4/3 + 4= 4 4/3 or 5 1/3 wood is needed for the border.

for the mirror, you will need the area= 4/3 * 2 = 8/3 sq yds or 2 2/3 sq yards is needed.

Is this one question correct
bazaltina [42]

Answer: 2/3ft or C

Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh.  Divide both sides by h: \frac{A(2)}{h}=b

A = 2/5

h = 6/5

b = ?

Next, we can plug the numbers into this equation: \frac{2/5(2)}{6/5}=b

Multiply 2 and 2/5: 4/5 / 6/5

Take the reciprocal of 6/5: 4/5 x 5/6 = \frac{20}{30}

\frac{20}{30} ÷ \frac{10}{10} = \frac{2}{3}
