Answer:
(1) 10m/s
(3) 5cm
(4) 100
(5) 4200 m3
(6) 1250 m2
Step-by-step explanation:
(1) Covert 180km into meters
180 x 1000 = 180000
Distance travelled per hour = 180000/5 = 36000
Distance travelled per second = 36000 / 60 / 60 = 10
Therefore, speed = 10m/s
(3) Since volume equals to length x breadth x height,
Breadth = volume / height / length
Therefore,
breadth = 120 / 8 / 3 = 5
(4) From what I understand, 40 = perimeter of the handkerchief
Since area = length x breadth ,
Area of handkerchief = 10 x 10 = 100
(5) The swimming pool is like a cuboid.
Area of cuboid = length x breadth x height
Area of swimming pool = 30 x 20 x 7 = 4200
(6) Area of a rectangle = length x breadth = 50 x 25 = 1250
