Question

the ratio of the legth of two sides of parallelogram is 2:5 and it's perimeter is 84 cm. find the length​

Answer 1

Answer:

Let the sides be =2x,5x

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

84=2(2x+5x)

84= 14x

$\frac{84}{14}$=x

6=x

So,

length =5x=5×6= 30cm

Breadth=2x=2×6= 12cm
