Step-by-step explanation:   3.(1) Side = 10m  Area of square = 10×10=100m^2  (2) Side = 21  Area of square = 21×21=441m^2  (3) Side = 0.5m  Area of square = 0.5×0.5=0.25m^2  (4) Side=4m  Area of square = 4×4=16m^2  4. (1) Breadth = 20m  Area of rectangle = 900m^2  L×B= 900  L×20= 900  L= 900/20=45  Perimeter = 2(L+B)= 2(45+20)=2×65=130  (2) Length = 26cm  Area of rectangle =962cm^2  L×B= 962  26×B= 962  B= 962/26= 37cm  Perimeter = 2(L+B)= 2(26+37)= 2×63=126
