Question

find the perimeter of the given image​

Answer 1

Answer:

111.4

Step-by-step explanation:

First Off ALL perimeter of square i.e. 20 x 4 + perimeter of semicircle i.e. 1/2 x 2 x pie x radius (10)

Answer 2

Answer:

The Perimeter of the given image is 91.4 mm

The Formula For Finding The Perimeter of semicircle is

πr+d

Here Semicircle is AB

ABCD is A Square So,All Sides Are Equal

Side DC=sideAB

According to Identical marks side DC=20 mm

So,Side AB=20 mm

The Radius Of Semicircle is 20÷2=10

Step 1:We will Find First Measuer Of Semicircle AB :

πr+d=3.14×10+20=51.4

Therefore ,The Measure Of The Semicircle Is 51.4

51.4-20=31.4,Because We Want To Measure The Perimeter

Adding All Sides Together:

20+20+20+31.4=91.4

Therefore the Answer is 91.4

I hope It Will Help You
