Question

the area of a square field is 4225 sq.m if one of its side is decreased by 2 what will be the decrease in its area​

Answer 1

Answer:

Area of square = a^2

4225 = a^2

$\sqrt{4225 = a } \\ 65 = a \\ a = 65 - 2 \\ a = 63 \\ area = {63}^{2} \\ area = 3969 \\ area \: decrease \: by \: = 4225 - 3969 \\ area \: decrease \: by = 256 \\ hence \: area \: is \: decrease \: by = 256$
