Answer:
Length is 182 cm and width is 158 cm.
Step-by-step explanation:
Given:
Perimeter of rectangle table = 680 cm.
Let the width of the table be
.
Now according to given length of the table is 24 cm more than the race the width
hence length =
.
But perimeter of rectangle = 2(length+width)
Substituting the values we get;

Hence width = 158 cm
Now, length = 24 cm + width = 24 cm + 158 cm = 182 cm
Hence the dimension of table are 182 cm and 158 cm.
If your looking for solutions their will be zero. Since 15+23+7=15+7 is false, there is no solution.
