Question

Find the perimeter of the shape

Answer 1

Answer:

You can draw a perpendicular in trapezoid on other side from semi circle.

Then it makes the figure - a right angled triangle with sides 7cm, 6cm & √85cm. A rectangle with length 10cm & breadth 6cm and a semi circle with radius 3cm.

Now its easy.

Perimeter of ∆ = 7 + 6 + √85

= (13 + √85) cm

Perimeter of rectangular part

= 2(10+6) = 32 cm

And perimeter of semi circle

= 3π

Hence the perimeter of given figure is sum of all

= (45+√85+3π) = 63.64 cm (approximately)
