Question

A child wants to make a design on a 64 cm * 64cm cardboard sheet .if he wants to use bindis along all edges of the square board such that there are 65 bindis on each side of square . Each bindi is at the same distance from the neighbouring bindi . How many bindis would he require for making the design around the cardboard

Answer 1

no. of bindis on each side = 65
no. of bindis on all 4 sides = 65*4 = 260

hope you find this helpful...:)

Answer 2

Number of Bindis on each side = 65

Thefore , there are 4 sides in cardboard.

So, number of Bindis on 4 sides = 65×4
= 260

But If we think , the corner most Bindis will overlap each other , So we must subtract 4 from the Total number of Bindis to obtain correct figure.

So, Total number of Bindis = 260-4 = 256

Answer → He requires 256 Bindis for making design around cardboard.
