Question

ABCD is a square with CD =( a+12 )cm and AD =(4a)cm. The perimeter of square is​

Answer 1

Answer:

256

Step-by-step explanation:

as one side is 4a and another is a+12

as side of square are equal

therefore 4a=a+12

4a-a=12

3a=12

a=4 (a+12=4+12=16),(4×4=16)

perimeter of square is 4xs

ie 16×4= 64m

hope it helps u

Answer 2

Answer:

We know that all sides of a square are equal. So, CD = AD

a + 12 = 4a

a - 4a = -12

-3a = -12

a= -12/-3

a = 4

Each side of square = 4*a = 4*4 = 16 cm. {as one side of square is 4a}

Perimeter = 4*side

4*16 = 64cm
