Question

Draw a rectangle of length 5cm and width 3cm

a- Draw a rectangle of the same area with length 6cm

b- Draw a square of area 15 cm²​

Answer 1

1. Draw a rectangle of length 5cm and width 3cm.

The long sides would be 5cm and the short sides would be 3cm.

2. Draw a rectangle of the same area with length 6cm.

It is looking for a rectangle that is 15cm^2. You already know your long sides are 6cm long. The formula for area is area=length x width. To find your width, your new equation will be area / length = width. You will then find that 15 / 6 = 2.5. Your short sides will be 2.5cm.

3. Draw a square of area 15cm^2.

A square has four equal sides. As a result, you need the square root of 15. The square root of 15 is about 3.87. All of your sides will be about 3.87cm long.
