Question

the perimeter of a rectangle PQRS is 70 cm of PQ:QR = 3:4 THEN FIND OR​

Answer 1

Let the sides of the rectangle be 3x >= 4x respectievely (As given 3:4)

Then ;

Perimeter of Rectangle = 2(1l + b) so; 2(3x + 4x) = 70 2(7x) = 70 7x = 70/2

= 35

then x = 35/7 theirfore x = 5

then side QR (As it is taken as the breadth)

=;

4x = 5x4 20
