Answer 1

Answer:

a = 42 cm b =10.5 cm c = 84 cm d = 21cm

Step-by-step explanation:

in figure a there are 4 quadrants then area of the four quadrant = 154 cm and the area of square = 196 cm

then area of shaded region = 196 - 154 = 42

in figure b

there is a quadrant with radius 7 cm then area of quadrant = 77/2 cm

area of square = 49 cm

then area of shaded region = 10.5

in figure c

we can easily see two circles with diameter 14 cm means radius 7cm

area = 308 cm

area of rectangle = 392 cm

area of shaded region = 84 cm

in figure d two quadrant with radius 7 v

cm are shown

then area of quadrants = 77 cm

then breadth will be equal to radius means 7 cm then area of rectangle = 98 cm

area of shaded region = 21

hope u will not mind the units
