Answer:
Length = 10cm
Width = 12cm
Step-by-step explanation:
let the width of the rectangle be x cm
then length of the rectangle =(x-2) cm
area of the rectangle= 120cm²
x(x-2)=120
x²-2x-120=0
x²-12x+10x-120=0
x(x-12)+10(x-12)=0
(x-12)(x+10)=0
x=12 or,x=-10
length can never be negative
therefore, x=12
length is 10cm
and width=12cm

625 cm3
Formula V1 * P1 = V2 * P2
V1 = 450 cm3
P1 = 125 kPa
P2 = 90 kPa
V2 = ?
V2 = (V1 * P1) / P2
V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3
6 : 11
the ratio 6 : 11 applies to all linear measure in the similar polygons
Both side lengths and perimeter are linear, hence
ratio of both is 6 : 11
