Question

when the length of each side of a square was increased by 10cm.its area becomes 36cm².what was the length of a side of the original square​

Answer 1

(X+10)^2=36

solve by this statement ,let orgnal side of square be x

Answer 2

Step-by-step explanation:

let the length of the square be x+10cm,

Length=x+10cm

Area of square =36cm square

we know that,

Area of square =l square or l×l

36=(x+10)^2

or, root under 36=x+10

or, 6=x+10

or, 6-10=x

or, x= - 4cm

Now, length of square =x+10

(putting the value of x= - 4 )

Length of square = - 4+10

= 6cm

Hence, the length of a side of the original square is 6cm
