The percentage of the area inside the square that is shaded is 55%.
<h3>What is the perimeter of the square?</h3>
Given:
The perimeter of the square is 20Cm
Each side of the square is = 5Cm
Area = ( Length x Width )
(5 x 5) = 25 =Area
Area = 25
Area of triangle 1 = (1/2) x 5 x (5 - 3) = 5 cm²
Area of triangle 2 = (1/2) x 5 x (5 - 3.5) = 6.25 cm²
Area of shaded portion = 25 - (5 + 6.25) = 13.75 cm²
Percentage of shade portion
= (13.75 cm² / 25 cm²) x 100%
= 55%
The percentage of the area inside the square that is shaded is 55%.

If Daniella is paying 15% of her salary as income tax, the other 85% should be her take-home pay. In this case, Daniella
wants to have at least $51,000 as take-home pay.
0.85 (Salary) = $51,000
Salary = $51,000 / 0.85
Salary = $60,000
Therefore Daniella should have at least a salary of $60,000.
