Question

A rectangle has a length of 8.2 cm and a height of 42 mm. What is the area of the square in square millimeters?

Answer 1

Answer:3,444 mm^2

Explanation:

1 cm is 10 mm, so 8.2 cm is 82 mm. 82 mm x 42 mm = 3,444 mm^2

Answer 2

The area of triangle is 3444 mm².

Explanation:

First, you have to convert the length of square into millimeters :

`1cm = 10mm`

`8.2cm = 10mm * 8.2`

`8.2cm = 82mm`

Next, you have to apply area of square formula, A = length×height :

`area = length * height`

`let \: length = 82,height = 42`

`area = 82 * 42`

`area = 3444 {mm}^(2)`
