New Learning Composite Mathematics Class 6 SK Gupta Anubhuti Gangal Perimeter and Area Chapter 14B Solution
Rules of Rectangle:
Area of Rectangle = Length x Breadth
If in Question there are Length is given and Area is given, you have to find Breadth. Then Breadth Area/Length
If in Question there are Breadth is given and Area is given, you have to find Length. Then Length Area/Breadth
(1) Rectangles
| Length | Breadth | Area |
| (a) 8 cm | 4 cm | 8 X 4 = 32 cm2 |
| (b) 12 m | 6 m | 12 X 6 = 72 m2 |
| (c) 10 cm | 7.5 cm | 10 X 7.5 = 75 cm2 |
| (d) 7 mm | 14 mm | 7 X 14 = 98 mm2 |
Area of Square = Side x Side= Side2
A Square has 4 side.
(2) Squares
| Each side | Area |
| (a) 3 cm | 32 = 9 cm2 |
| (b) 10 cm | 102 = 100 cm2 |
| (c) 5 mm | 52 = 25 mm2 |
| (d) 1.6 cm | 1.62 = 2.56 cm2 |
