Question

2. Find the permeter of the shaded part of each of the figures given below.​

Answer 1

14 pie = 43.982

Explanation:

the corners of the square can be identified as a quarter of a circle
1/4 ○ together they make a full circle
we can measure the whole circle's perimeter to get the shape's
= 2 Pie r
R= 7 cm
so the circle's whole perimeter = 14 pie = 43.982= the shape's perimeter

Answer 2

shaded part area = square area - 4*quarter circular area

r = 7

= 14² - (4*1/4*π*r²)

196-153.86 = 42.14 cm²
