Answer 1

See attachment

Explanation:

Given

`Side\ 1 = 10cm`

`Side\ 2 = 12cm`

`\theta = 90^\circ`

Required [Missing from the question]

Draw the top of the cake

See attachment for reference.

From the attachment,

`2cm = 1\ unit`

So:

`Side\ 1 = 10cm`

`Side\ 1 = 5 * 2cm`

Substitute
`2cm = 1\ unit`

`Side\ 1 = 5 * 1unit`

`Side\ 1 = 5\ units`

`Side\ 2 = 12cm`

`Side\ 2 = 6 * 2cm`

Substitute
`2cm = 1\ unit`

`Side\ 2 = 6 * 1unit`

`Side\ 2 = 6\ units`

This means that, the given side lengths will be represented by 5 units and 6 units on the grid, respectively.
