Question

A rectangular plot has the ratio of 5:3 between length and breath. If the perimeter of the plot is 320 mtr. What’s the area of the plot? ​

Answer 1

LET THE LENGTH AND BREADTH BE 5X AND 3X

SO NOW, Perimeter = 2 ( l + b)

320 = 2(5x + 3x)

320 = 16x

x = 20

Area of the plot = 5x X 3x = 15x²

15x² = 15 x 400 = 6000 m²

pls mark as brainliest

Answer 2

Answer:

let the length and breadth be 5x and 3x

therefore, 2(5x+3x)=320

or, 16x=320

or, x= 20

length= 5x

=5×20

=100 m

breadth=3x

=3×20

=60 m

area= length×breadth

=100×60

=6000 sq.m.
