Perimeter of rectangle = 80 m
Let x be the length and 16m breadth.
We know, perimeter = 2 [length + breadth]
75 = 2(x + 16)
75 = (2x + 32)
Or x = 21.5
Thus,
Length of the rectangle is 21. 5 meter
Again,
Area of the rectangular plot = Length X Breadth
= (16 × 21.5)
= 344
So, Area of the rectangular plot is 344 cm2
Therefore, length of rectangle is 21.5 m and the area is 344 m2.
