Let the side of  one square be x.    Area = x*x = x²

Then the side of other square  would be 2x ,   Area = 2x*2x = 4x²

Combined area = x² + 4x²  = 5x²

This combined area = 45 cm²

Therefore  5x²  = 45   Divide both sides by 5
                  x²  =  45/5
                  x²  = 9        Take square root of both sides
                  x   =  √9
                  x  = 3

Length of larger square is 2x  = 2*3 = 6 cm
Length of larger square = 6cm

The perimeter of a parallelogram is 56 meters the width of the parallelogram is 8 meters less than its length find the length of
Dimas [21]

Answer:

length = 18 mt

Width = 10 mt

Step-by-step explanation:

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

Hence

y=x-8

or x-y=8   ---(B)

Adding A and B

2x=36

x=18

y=x-8

y=18-8=10

Hence length = 18 mt

Width = 10 mt
