Question

The area of a rectangular plot is 460m. If the length of 15percent more than its breadth find the perimeter of the plot

Answer 1

Answer:

86m

Step-by-step explanation:

Area = 460m²

Let the breadth be x

then Length = x + 0.15x = 1.15x

Area = 1.15x²

1.15x² = 460

x² = 460/1.15

x² = 400

x = 20m

therefore breadth = 20m

and length = 1.15 × 20 = 23m

Perimeter = 2(23+20) = 2 × 43 = 86m
