Tomas has a garden with a length of 2.45 meters and a width of 5/8 meters. Use benchmarks to estimate the area and perimeter of
Alchen [17]

Answer: The area is  1 1/4. The perimeter is 6.

Step-by-step explanation: 2.45 is about 2.5.   5/8 is about 1/2.  To find the area we need to multiply length times width.  2.5 is  2 and 1/2 which is 5/2. 5/2 times 1/2 is 5/4. To simplify it divide 5 by 4 which is 1 with remainder 1. 5/4 is 1 1/4. Therefore the area is 1 1/4 meters squared. To find the perimeter we have to add length + length + width + width. . 2.5 is the same thing as 2 1/2.  5/8 is about 1/2 if we use benchmarks.     2 1/2 + 2 1/2 +  + 1/2 + 1/2 is 6. The perimeter is 6.

PLEASE HELP ME ASAP!!!!

<u>Part A</u>

<u />\overline{AC} and \overline{BD}

<u>Part B</u>

Diagonals of a parallelogram bisect each other, so

BE=ED \implies 2x+3=3y-4 \implies 3y=2x+7 \implies y=\frac{2}{3}x+\frac{7}{3}\\\\AE=EC \implies y+4=4x-6 \implies y=4x-10

Solving by substitution,

\frac{2}{3}x+\frac{7}{3}=4x-10

Multiplying both sides by 3,

2x+7=12x-30\\\\37=10x\\\\x=3.7

So, y=\frac{2}{3}\left(\frac{37}{10} \right)+\frac{7}{3}=\frac{24}{5}

<u>Part C</u>

<u />BE=ED=2(3.7)+3=10.4\\\\AE=EC=4(3.7)-6=8.8

\therefore BD=2(10.4)=20.8, AC=2(8.8)=17.6
