Answer:

1. 15.72m²

2. 48dm²

3. 4m²

Explanation:

1.

area of unshaded circle=

r=3m. πr^2. (22/7)×3×3= 28.29

area of shaded circle

radius= total radius- unshaded circle radius

r=5m-3m = 2m

Area= πr^2. (22/7)×2×2= 12.57

therefore area= unshaded-shaded

28.29-12.57= 15.72

2.

area of unshaded= area of square = L²

8×8=64

area of shaded= length= 8-2-2= 4

4×4= 16

total area =

64-16= 48

3.

area of triangle= (b×h)/2

(7×6)/2= 42/2= 12

area of rectangle= L×b

4×2= 8

area=12-8= 4
