Best answer

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.
