The breadth of a plate increases from one corner to other in a continuous manner.
Breadth of the plate changes from 10 cm. to 20 cm. and length of the plate is 50 cm., then area of the plate is
We can assume that the plate is formed of three geometries
First is a right angled triangle of two perpendicular sides 50 & 5 cm.
Second is a rectangle of dimensions 50 & 10 cm.
Third is a right angled triangle of two perpendicular sides 50 & 5 cm.
Total area of the plate is 1/2(50+5) + 50×10 + 1/2(50+5) = 750
A cylinder of radius and height both equal to 10 cm. made by paper is unfolded to form a plane sheet of paper.
If circumference of a circle is 2ΠR, then area of plane paper sheet is-
Rate list of some liquids purchased by Subham is
Item Rate per litre Amount required in litres
Milk 20/- 5
Oil 80/- 1
Cream 120/- 0.5
A shopkeeper offers a discount of 10%, 20% and 30% in the rate of following items. These discounts
