Concept
In our home we have different objects of different shapes, so we are asked to determine the area, perimeter , breadth, height and volume of the objects.
Given
five objects -
1) pencil box in rectangular shape
2) mirror in square shape
3) showpiece in triangular shape
4) pouch in cylindrical shape
5) bed in rectangle shape.
Find
the area, length, breadth, height and volume of the objects mentioned above.
1) pencil box in rectangular shape
length = 12cm
breadth = 5cm
area = l×b = 12 × 5 = 60 cm
perimeter = 2(l₊b) = 2(12₊5) = 34 cm
2) mirror in square shape
side = 7 cm
area = side² = 7² = 49 cm
perimeter = 4 × side = 4 × 7 = 28 cm
3) showpiece in triangular shape
base = 6 cm
height = 12 cm
area = 1/2 ×b × h = 1/2 = 6 × 12 = 36 cm
perimeter = a₊b₊c = 28 cm
4) pouch in cylindrical shape
V = Area of base × height
= 30 cm2 × 6 am
= 180 cm3
5) bed in rectangle shape.
length = 100 cm
breadth = 50 cm
area = l×b = 100×50 = 5000 cm
perimeter = 2(l₊b) = 2(100₊50) = 300 cm
