Question

if the perimeter of parallelogram is 21cm and adjacent sides are in the ratio 3 is to 4 find the sides of parallelogram

Answer 1

let the sides be 3x and 4x ..
perimeter = 2(l+b) cm
= 2(3x+4x)cm
= 14x cm
but perimeter given 21 cm
21 cm = 14 x cm
x cm = 3/2 cm
Side 1 = 3x = 3*3/2cm= 4.5 cm
Side 2 = 4x = 4*3/2cm=6cm
