Answer:
let us find the area of square
given
side of square ABCD=14cm
area of square ABCD =(side)^2
(14)^2 = 96cm
let us mark the shaded region
as. | , || , ||| and |√
diameter of semicircle = side of square=14cm
radius of semicircle = side /2
14/2=7
area of semicircle AD 1/2×area of circle
1/2×πr^2
1/2×22/7 ×(7)^2
= 11×7=77cm^2
area of all semicircle =77cm^2
area of region |+area of region |||
area of square ABCD
- ( area of semicircle AD + area of semicircle BC)
area of region || + area of region |√
area of square ABCD
- ( area of semicircle AB + area of semicircle CD
so, area of region (|+||+|||+|√)
= 2(area of square ABCD ) - ( area of semicircle AD+BC+AB+CD
puting the values
2(196)-(77+77+77+77)
200-4×77
392-308
= 84cm^2
