Answer 1

Answer:

a] square

2. 38

Step-by-step explanation:

Answer 2

Step-by-step explanation:

HEY MATE YOUR ANSWER IS HERE ^_^

(1) THE SQUARE IS A REGULAR QUADRILATERAL.

(2) PERIMETER = 2(12 + 7) = 38 cm

(3) THE OPPOSITE ANGLE OF PARALLELOGRAM IS SAME ∠A = ∠C

(4) THE SUM OF ADJACENT ANGLES IN A PARALLELOGRAM IS 180°

70 + ∠B = 180° ⇒ ∠B = 110°

(5) THE LENGTH OF BOTH DIAGONAL'S IS SAME ∴ BD = 10 cm

(6) EACH ANGLE OF A SQUARE IS RIGHT ANGLE.

(7) TRIANGLE IS NOT A QUADRILATERAL.
