Question

the ratio of two sides of a 11 parallelogram is 5:3 if its perimeter is 256 cm find the lengths of the sides of the 11 parallelogram​

Answer 1

Answer:

1st side : 80

2nd side : 48

Step-by-step explanation:

$perimeter = 2(a + b) = 256$

if one side is 5x and other is 3x then

$perimeter \: = \: 2(5x + 3x)$

$2(5x + 3x) = 256$

$5x + 3x = 256 \div 2 = 128$

$8x = 128$

$x = 128 \div 8 = 16$

then 1st side

$5x = 5 \times 16 = 80$

second side

$3 x = 3 \times 16 = 48$
