Answer
the length is 20 cm and breadth is 16cm
Step-by-step explanation:
let, 2(a+b)= 72( as its the formulae of circumference)
here a is the length and b is the breadth
now total area is ab
according to the question
a(b-6)= ab-120
or -6a= - 120
so length is 20 cm
now by putting the value in the 1st eq we get
2(a+b)=72
or(a+b)=36
or 20+b=36
so breadth is 16 cm.
length is 20cm and breadth is 16 cm
(u can verify that easily)
thank u
Answer:
Step-by-step explanation:
Distribute:
Y+-3+(-2)(x)+(-2)(1)
Y+-3+-2x+-2
Combine like terms
Y+-3+-2×+2
(-2×)+(y)+(-3+-2)
-2x+y+-5
60*5= 300
or
60/.2= 300
60 minutes is 20% of 300 minutes
