Question

if the ratio of a rectangle is 3:4 the length of rectangle is 1 then what will be the width​

Answer 1

Step-by-step explanation:

The length and width of the rectangle are in a ratio 3:4, so the sides can be written as 3x and 4x.

So, Area = (3x).(4x)=300

12x

=300

x

=

12

300

x

=25

x=5

Then length =3x=3×5=15cm

width =4x=4×5=20cm

Diagonal length of a rectangle =

+w

=

=

225+400

=

625

=25cm
