Question

Please answer question with answer

Answer 1

48
`cm^(2)`

Explanation:

1. We need 2 integers (full number) when added gives us 7

this is 4 and 3

2. so the width of the rectangle is 3cm and the length is 4cm

3. to find one area of a rectangle we do

4cmx3cm= 12
`cm^(2)`

4. There is 4 rectangles, so we do

4x12
`cm^(2)`= 48
`cm^(2)`

5. so the total area of the pattern is

= 48
`cm^(2)`
