Answer 1

Answer:

1st diagram ans = 12 sq. cm

EXPLANTATION = 1 square size is 1 cm

and there r 12 squares so

12 squares × 1 cm = 12 sq cm

2nd diagram ans = 22 sq .cm

EXPLANATION= there r total 28 squares are shaded with pink colour but there are only 22 squares are shaded full with pink colour

don't count that squares which r half shade

only 22 squares r there that r fully shades so , that's why 22 sq.cm

AND

THAT IS IRREGULAR SHAPE

3rd diagram answer = 7 sq. cm

EXPLENTATION = total 27 squares r shaded

but only 7 squares r there that r fully shades

so , the answer is 7sq.cm
