Answer 1

Answer:

whattttt/////ttttttt????

Answer 2

Answer:

(a) 20 cm

Step-by-step explanation:

L = 5 cm, W = 1 cm

Rectangular perimeter is 2(L+ B)

= 2(5 + 1 )

=2(6)

= 12

So, From this rectangular make plus sign

Therefore , perimeter of square is minus from two rectangular perimeter .

• Two rectangular perimeter = 12 x 2 =24
• Perimeter of square which formed in plus sign = 4 W = 4 x 1 = 4

Plus sign perimeter = 24 - 4

= 20
