Question

ABCD is a square with AB =(x+16)cm and BC = 3x cm. The perimeter of the square is? ​

Answer 1

Step-by-step explanation:

perimeter = 4× l

also all sides of square are same!

AB = BC

x +16 = 3x

2x = 16

x = 8

perimeter = 4× l

= 4× 3(8)

= 4×24

= 96 cm

Answer 2

Answer:96

Step-by-step explanation:

since ABCD is asquare the sides are equal

x+16=3x

Therefore, x=8

Therefore AB=BC=24

But perimeter of square is P=4a

P=4×24

P=96
