Please solve 3,4 and 5

Dear Student,

4) Length of rectangle = 16 cm
    Breadth of rectangle = 5.5 cm

Area = length x breadth = 16 cm x 5.5cm = 88 cm^2

New length = (16-3.5) cm = 12.5 cm

New breadth = (5.5 + 1.5)cm = 7 cm

New area = (12.5 x 7) cm^2 = 87.5 cm^2

Kindly ask the rest of the questions in separate threads.

Regards
