35 cm
To find the area of a rectangle, you multiply the length by the width. In this case, the width is 7cm and the length is 9cm. So, the area would be 7cm x 9cm = 63 square centimeters.
It is: 3*7 = 21cm
What is the are for a rectangle of 13cm and 7cm
area= 7cm x 7cm = 49cm^2

24.5 cm sq
It is: 3*7 = 21cm
The area for a 7cm by 8cm is 56.
It is: 4*7 = 28 square cm
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
What is the are for a rectangle of 13cm and 7cm
The area of a rectangle is calculated by multiplying the length by the width. 7cm x 3.5cm = 24.5 cm2 - cm2 = centimeters squared
24.5 cm2 - Simply multiply the two known values together !
area= 7cm x 7cm = 49cm^2
