an error 5 % in excess is made while measuring the side of a square. what is the percentage of error in the calculated area of the square? Select the correct option
A) 4.05 %  B) 4.02 %  C) 4 %  D) 10.28 %  E) 2 %
<gadget id="calculator">100 + 5</gadget>
<output>105</output>

<gadget id="calculator">105 ** 2</gadget>
<output>11_025</output>

<gadget id="calculator">100 ** 2</gadget>
<output>10_000</output>

<gadget id="calculator">11_025 - 10_000</gadget>
<output>1_025</output>

<gadget id="calculator">1_025 * 100</gadget>

<output>41/4 = around 10.25</output>

<result>D</result>
an error 5 % in excess is made while measuring the side of a square. what is the percentage of error in the calculated area of the square?
divide(multiply(subtract(square_area(add(const_100, 5)), square_area(const_100)), const_100), square_area(const_100))
"percentage error in calculated area = ( 5 + 5 + ( 5 ã — 5 ) / 100 ) % = 10.25 % answer : d"
