Question

if the area of rectangle is 48m^2n^2 and lenght os 8m^2n^2 find the breath​

Answer 1

Step-by-step explanation:

How many rectangles can be drawn with 36 cm as the perimeter, given that the sides are positive integers in cm ?

Solution :

Perimeter = 36

⇒ 2 ( l + w ) = 36

⇒ l + w = 18

Since length and width are positive integers in centimeters. Therefore, possible dimensions are :

( 1, 17 )cm , ( 2, 16 ) cm , ( 3, 15 ) cm, (4 , 14) cm, ( 5,13) cm, ( 6, 12) cm , ( 7, 11) cm, ( 8, 10 ) cm, ( 9, 9) cm.

Hence, there are 9 rectangles.
