Answer 2

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
