Question

In square ABCD, AB = 4x -8, BC = 2x+2. Find the perimeter of the square

Answer 1

Step-by-step explanation:

all sides of a square are equal therefore, AB= BC

4x-8 = 2x+2

4x-2x = 2+8

2x = 10

x = 5

substitute x=5 in 4x-8

therefore 4x-8 = 12

side of the square is 12units

perimeter of a square = 4× side

therefore, perimeter = 4×12 = 48
