Question

22. The length of two adjacent sides of parallelogram is 2x and 6x. Its perimeter is 480 cm.​ find the value of x

Answer 1

Answer:

x = 30

Step-by-step explanation:

perimeter of parallogram = 2 ( l + b )

480 = 2 ( 2x + 6x )

480 = 2 × 8x

480/2 = 8x

8 x = 240

x = 240 / 8

x = 30

Answer 2

Answer:

x = 30

Step-by-step explanation:

perimeter of parallogram = 2 ( l + b )

480 = 2 ( 2x + 6x )

480 = 2 × 8x

480/2 = 8x

8 x = 240

x = 240 / 8

x = 30
