Question

9. There are 3 ribbons each of length 240 cm. They are used to stitch along the sides of three banners as shown below:

a) A triangle
b) A square
c) A regular hexagon

Find the length of the side of each banner.​

Answer 1

Answer:

Step-by-step explanation:

Given:  ribbons each of length=240 cm

Now, each ribbon is stitched along the lengths of a triangle.

We have, sum of all the sides of a triangle is equal to the length of a ribbon.

Let the side of triangle=x

x+x+x=240

x=80 cm

Second ribbon is stitched along a square.

Let the side of square be  y cm

We have, perimeter of square=4xside

240=4y

y=60 cm

Le the side regular hexagon=k

We have, perimeter of a regular hexagon=6xside

6k=240 cm

k=40 cm

Therefore, length of each side of banners are 80 cm, 60 cm, 40 cm.
