Answer:
The GCF of 40 and 63 can be obtained like this:
The factors of 40 are 40, 20, 10, 8, 5, 4, 2, 1.
The factors of 63 are 63, 21, 9, 7, 3, 1.
The common factors of 40 and 63 are 1, intersecting the two sets above.
Step-by-step explanation:
length = 18 mt
Width = 10 mt
Let the length of the field be x
width of the field be y
Hence
P=2(x+y)
P=56 (given)
56=2(x+y)
Dividing both sides by 2 we get
x+y=28 ---(A)
Also given that width of the parallelogram is 8 meters less than its length
y=x-8
or x-y=8 ---(B)
Adding A and B
2x=36
x=18
y=18-8=10
Hence length = 18 mt
yeah I think it is A thank me later
y = 2
x= -1+y
2x-y=0
2(-1+y)-y=0
-2+2y-y=0
-2+y=0
-2+2+y=0+2
y=2
hope it's helpful ❤❤❤❤
THANK YOU.
