Question

The length of a rectangular plot is 5 times its breadth. If the perimeter of the plot is 120 m. Find the dimensions of the plot.

Answer 1

Answer:

Formula for perimeter:

2x + 2y = 120m

Taking x to be length and y to be breath substitute in the new variable

2x + 2/5 x = 120

Tidy up

12/5 x = 120

12x = 600

X = 50m

Then breath is 1/5 x so

Y = 10m

2x + 2y =120

2(50) + 2(10) = 120
