Hello help me with this question thanks in advance

Answer 11 :-

We have,

In square all sides of squares are equal

The perimeter of square

Thus, The perimeter of square is 20 cm

Hence, Option C is correct .

Answer 12 :-

We have,

In square, diagonals are equal and bisect each other at 90°

Here,

Thus, The MT is 7cm long

Hence, Option C is correct .

Answer 13 :-

We have to find the measure of Angle MAT

All angles of square are 90° each

From above

Thus, Angle MAT is 90°

Hence, Option B is correct .

Answer 14 :-

We know that,

All the angles of square are equal and 90° each

Therefore,

Thus, Angle MHA is 45°

Hence, Option A is correct

Answer 15 :-

Refer the above attachment for solution

Hence, Option A is correct

Answer 16 :-

Both a and b

The median of isosceles trapezoid is parallel to the baseThe diagonals are congruent

Hence, Option C is correct

Answer 17 :-

In rhombus PALM,

All sides and opposite angles are equal

Let O be the midpoint of Rhombus PALM

In ΔOLM, By using Angle sum property :-

Now,

OL is the bisector of diagonal AM

Therefore,

Thus, Angle PLA is 55° .

Hence, Option C is correct
