Question

ABCD is a rectangle where the ratio of the length of ab and BC is 4:3 if it's badminton is 140 cm then the length of its diagonal is​

Answer 1

Answer:

50 meters

Step-by-step explanation:

so if sides are in ratio = 4/3

let them be = 4x and 3x

now perimeter is 140 cm

so = 2 ( 3x+ 4x) = 140 cm

= 14 x = 140 cm

x = 10

now its sides = 3x = 30

= 4x = 40

so as it is a rectangle and it has all angle at 90 degree its side will be perpendicular and other side will be base

so , d^2 = (30)^2 + (40)^2

d^2 = 900 + 1600

d^2 = 2500

d = 50 m
