Question

find the perimetre ,which ans is 50 cm please solve it

Answer 1

Perimeter = sum of all sides

Perimeter of the figure

==> 7 cm + 7 cm + 7 cm + 7 cm + perimeter of the curves

==> 28 cm + 4 × 1/4 × 2 πr [ 4 quadrant's perimeter ]

==> 28 cm + 1 × 2 × 22/7 × 7 cm

==> 28 cm + 2× 22 × 1 cm

==> 28 cm + 44 cm

==> 72 cm

The perimeter is 72 cm

Hope it helps :)

Answer 2

Answer:

Step-by-step explanation:Given: SP║RQ, ∠R = 90° and ∠Q = 130°.

To find: The measure of ∠P.

Answer:

It is given that SP║RQ. So let us assume that PQ is the transversal.

Therefore, ∠P + ∠Q = 180° (Co - interior Angles are Supplementary)

∠P + 130° = 180°

∠P = 180° - 130°

∠P = 50°

Now let us assume that SR is the transversal.

Therefore, ∠S + ∠R = 180° (Co - interior Angles are Supplementary)

∠S + 90° = 180°

∠S = 180° - 90°

∠S = 90°
