Answer:
9.2 cm and 15% increase
Step-by-step explanation:
1.15*8 = 9.2
percentage increase
new square = 9.2*9.2 =84.64
old area=8*9.2 = 73.6
percentange increase = (84.64-73.6)/73.6 = 15%
10 and 2/3 = 32/3
32/3 x 8 = 256/3
256/3 = 85.33333333333 repeating
It is the last one (x+3)2
Use proportion to solve this.
