Answer:
ATQ,
4x + 7x + 4x + 7x = 121 cm
22x =121 cm
x = 5.5 cm
Hence, the sides are 22cm, 38.5 cm, 22cm, 38.5 cm
Let the sides be 4x, 7x, 4x and 7x respectively.
(because opposite sides are equal.)
So, 4x+4x+7x+7x=121
8x+14x=121
22x=121
x=121/22
x=11/2
Therefore the sides are
4×11/2=22cm.
22cm.
7×11/2=77/2=38.5cm
38.5cm.
respectively.
