    Step-by-step explanation:

    perimeter of first painting =2(42+42)=2*84=168 cm

    perimeter of second painting =2(60+36)=2*96=192 cm

    perimeter of third painting =2(84+24)=2*108=216 cm

    total wood required =168+192+216

    =576cm

    hope this helps you

    Answer:

    Total 576 cm wood required to frame all paintings

    Step-by-step explanation:

    1). First painting =

    42cm by 42 cm

    2). Second painting =

    60cm by 36cm

    3). Third painting =

    84cm by 24cm

    First find the perimeter

    As we know,

    Formula of perimeter = 2 ( length + width)

    So,

    1). 2 ( 42 + 42)

    ➨ 2 × 84

    168

    2). 2 (60 + 36)

    ➨ 2 × 96

    192

    3). 2 (84 + 24)

    ➨ 2 × 108

    216

    According to question:

    ➨ 168 cm + 192 cm + 216 cm

    576 cm

    Therefore,

    Total 576 cm wood required to frame all paintings
