Answer:

the side of a square is 45 m

Step-by-step explanation:

The computation of the side of the square field that contains the similar area as compared with rhombus is given below:

As we know that

Area of rhombus = Base × Altitude

= 81 × 25

= 2025

And, area of Square = Side × side

2025 = side^2

side = √2025

= 45m

Hence, the side of a square is 45 m

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

$\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15$

Step 2: Divide the decrease by the original number

$1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2$

Step 3: Multiply the result by 100 to get a percent decrease

$0.2 \times 100\\\\= 20$

Therefore, the percent decrease of the price of paper per package is 20%

<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>
