Answer 1

Area of rectangle = lb

= 21×10.5

= 220.5

then,

LM/3

21/3

7

so,

diameter of big semi circle = 14

diameter of small semi circle = 7

area of big semi circle = 1/2×22/7×7×7

= 77

area of small semi circle = 1/2×22/7×3.5×3.5

= 1/2×22/7×35/10×35/10

= 19.25

then ,

area of whole shaded region = 19.25+77

= 96.25

a/q,

area of shaded region = 220.5 - 96.25 = 124.25
