Question

measure of two adjacent sides of a rectangle are in the ratio 5 ratio 3 if the perimeter of the triangle is 80 m find its length and breadth

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Length (l) / breadth (b) = 5/3

Length = 5b/3. (1)

Perimeter = 2( l + b ) = 80

= 2 ( 5b/3 +b) = 80. ( using (1) )

= 2 [ ( 5b + 3b ) 3 ] = 80

= 8b / 3 = 40

= 8b = 120

= b = 15 cm

using b = 15,

l = 5/3 x 15 = 25 cm
