Question

a rectangle is 40cm long and 30cm wide, use a scale of 1cm to represent 10cm to draw a scale diagram of the rectangle on the grid.​

Answer 1

Hello mariamhifzur!

Given,

A rectangle is 40 cm long & 30 cm wide. So,

• Length = 40 cm

• Width = 30 cm

Now, using a scale of 1 cm to represent 10 cm we need to draw a scale diagram of the rectangle on the grid.​

At first we need to convert the measurements of the rectangle in real life to its scale measurements.  In the question given, we need to convert 10 cm to 1 cm in the scale. So,

• Length = 40 cm = 4 cm (in the scale figure)
• Width = 30 cm = 3 cm (in the scale figure)

Now, suppose each grid is equal to 1 cm. Then, we can take the measurements as :

• Length = 4 cm = 4 boxes/grids

• Width = 3 cm = 3 boxes/grids

Let's draw the figure now. Our rectangle looks like ... (see the attachment).
