Question

Find the area 9cm 4 cm 3cm 6cm 12cm​

Answer 1

132cm²

Explanation:

1.) You chop off the tiny rectangle on the left side and think of it as a separate problem.

2.) To find the area of the tiny one, you multiply the length and width ( 6cm and 4cm). Now you have the area of the tiny rectangle, which is 24cm².

3.) Now, you have to find the area of the big rectangle. You multiply length and width (9cm and 12cm) and you have the area of the big rectangle, 108cm².

4.) Finally, you add the areas of both rectangles (24cm² and 108cm²) to get 132cm².

Answer 2

`A_(total) = 132\ cm^2`

Explanation:

Step 1: Determine the area of the left rectangle

`A = l * w`

`A = 9\ cm * 12\ cm`

`A = 108\ cm^2`

Step 2: Determine the area of the right rectangle

`A = l * w`

`A = 4\ cm * 6\ cm`

`A = 24\ cm^2`

Step 3: Determine the total area

`A_(total) = 108\ cm^2 + 24\ cm^2`

`A_(total) = 132\ cm^2`

Answer:
`A_(total) = 132\ cm^2`
