here is your answer thank you

Answer 2

Answer:

The error in the measurement of its area is 2%

Explanation:

Consider side of a rectangle ‘’a’’ and ‘’b’’ so area ‘’A’’ will be ab.  

Consider a error in side ‘’a’’ is Δa and the error in side ‘’b’’ is Δb than error in measurement of area ΔA will be ΔA/A = Δa/a + Δb/b  

In the question its given error is 1% so,

Δa/a = 1/100 and Δb/b = 1/100  

So, ΔA/A = 1/100 + 1/100 = 2/100  

Area, ΔA = 2%
