A scenery is painted on a paper 44cm long and 30cm wide such that there is a margin of 2cm along each of its sides. Find the total area of the margin.

280 cm²

Step-by-step explanation:

The computation of the total area of the margin is shown below:

Given that

Length = 44 cm

Breadth  = 30 cm

Area of the cardboard = 44 × 30 cm² = 1,320 cm²

Now

Length of the painting eliminating the margin is

= [44 - (2 + 2)] cm

= 40 cm

And,

Breadth of the painting eliminating the margin is

= 30 - (2+ 2)

= 26 cm

Now

Area of the painting eliminating the margin is

= (40 × 26) cm²

= 1,040 cm²

And, finally the total area of the margin is

= (1,320  - 1,040) cm²

= 280 cm²

- 70

this is the answer for you hope it

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
