Question 1046778
Let the original area be A, the original side be s, and the new side be x:
A = s^2
If the area increased by 69%:
(1+0.69)A = (1.69)A
To find the length of the new side:
x^2=1.69A
Since A = s^2:
x^2 = 1.69l2
Taking the square root of both sides we get:
x = 1.30
x = (1+0.3)s
The increase in length is 0.30 or 30%
