The perimeter is the sum of the sides. So if a square has a side of length 1, its perimeter is 1+1+1=1 = 4 If a square has a side doubled to length 2, its perimeter is 2+2+2+2 = 8, or double what it was before. Mathematically, if each side is length x it perimeter is x + x + x = X = 4x If each side is length 2x, its perimeter is 2x +2x+2x+2x = 8x

Let the length be known as x: 2(x+4) = 105 2x+8 = 105 2x = 105-8 2x = 97 x = 48.5 Length = 48.5 units
Let the length be 2x+7 and the width be x: 2(length+width) = perimeter 2(2x+7+x) = 128 4x+14+2x = 128 4x+2x = 128-14 6x = 114 x = 19 Therefore: length = 45m and width = 19m Check: 45+45+19+19 = 128m

Let the length be x:- 2(x+4.2) = 25 2x+8.4 = 25 2x = 25-8.4 2x = 16.6 x = 8.3 units of length Check:- Perimeter = 8.3+8.3+4.2+4.2 = 25

for area we should multiple length X breadth for perimeter we should do 2x(LxB)
Let the breadth = xSo, length = 2x+1Thus perimeter will be,2(2x+1+x)=122= 6x+2=122So, 6x=122-2=120So, x= 120/6=20Therefore length=2x+1=2(20)+1=41
The perimeter can be written as 2x + 2y = P where the x is length and y is width we know that y = x + 58 so 2y = 2x + 116 2x + 2x + 116 = 260 4x=148 x=37 37+58=95 y=95
Let the length be known as x: 2(x+4) = 105 2x+8 = 105 2x = 105-8 2x = 97 x = 48.5 Length = 48.5 units
Let the length be 2x and the width be x: Perimeter = 2(2x+x) = 84 4x+2x = 84 6x = 84 Divide both sides of the equation by 6 to find the value of x: x = 14 Therefore: length = 28cm and width = 14cm
If the rectangle has a width of x inches, and a length of x + 16 inches, then its perimeter equals to 2x + 2x + 32 or 4x + 32. If x = 14, then x + 16 = 30. So the perimeter of rectangle becomes 2(14) + 2(30) = 28 + 60 = 88 inches.
Let the length be 2x+7 and the width be x: 2(length+width) = perimeter 2(2x+7+x) = 128 4x+14+2x = 128 4x+2x = 128-14 6x = 114 x = 19 Therefore: length = 45m and width = 19m Check: 45+45+19+19 = 128m
let the length be 'x' and the breadth be 'y' then area = xy and perimeter = 2x+2y Solve the simultaneous linear equations by given area and perimeter. Regards, A Pakistani!
