- The length of sides of given parallelogram is 7cm and 15 cm .
Ⲋⲟⳑⳙⲧⳕⲟⲛ :
Let us assume that the length of one side of parallelogram be x and the other sides of the parallelogram be y .
On the basis of given information we can say that:
- One side of a parallelogram is 8cm more that the other
ㅤㅤㅤ➙ x + 8 = y
- Perimeter of parallelogram = 44 cm
- Perimeter = sum of all sides
- As parallelogram has 2 equal sides , we can say that ; Perimeter of parallelogram = 2 ( l + b )
Ⲧⲏⲉⲅⲉ⳨ⲟⲅⲉ,
ㅤㅤㅤ➙ 2 ( x + y ) = 44
ㅤㅤㅤ➙ 2 ( x + x + 8 ) = 44
ㅤㅤㅤ➙ 2 ( 2x + 8 ) = 44
ㅤㅤㅤ➙ 4x + 16 = 44
ㅤㅤㅤ➙ 4x = 44 - 16
ㅤㅤㅤ➙ 4x = 28
ㅤㅤㅤ➙ x = 28 / 4
ㅤㅤㅤ➙ x = 7 cm
Since,
ㅤㅤㅤ➙ y = x + 8
ㅤㅤㅤ➙ y = 7 + 8
ㅤㅤㅤ➙ y = 15 cm
ㅤㅤㅤㅤㅤ~Hence, the sides of parallelogram are 15cm , 15 cm, 7 cm and 7cm !
