Question

the shorer side of a parallelogram is 8.4 cm and the longer side is 3/2 of the shorter side find the perimeter of the parallelogram

Answer 1

Shorter side = 8.4 cm

Longer side = 3* shorter side / 2

= 3*8.4 / 2

= 3* 4.2

= 12.6 cm

Perimeter = 2( Sum of adjacent sides)

= 2 * (8.4 + 12.6)

= 2 * 21

= 42 cm

Answer 2

Shorter side = 8.4 cm

Longer side =
$\frac{3}{2} \times \frac{84}{10}$

= 12.6 cm

Perimeter of parellalogram = side + side + side + side or 2 ( longer side + shorter side)

= 2 ( 12.6 + 8.4 ) cm

=42 cm
