Question

length and breadth of a rectangle are in ratio 4:3 . If measure of each of its diagonal is 10 cm . then it's perimeter is​

Answer 1

Step-by-step explanation:

let us take 10 as hupotenuese and adj side and opp sside as 4x and 3x as they were in ratio

so accordingly 10^2 = (4x)^2+(3x)^2

100=16x^2+9x^2

100=25x^2

4=x^2

x=2 since side can't be negetive

so the side are 8 and 6 cm respectively

then perimeter =2(l+b)

=2(8+6)

=2(14)

=28

hence perimeter is 28 cm
