Question

If the table cloth are all 1,5m long,what is the length of the sides of the table cloth?use the theorem of Pythagoras

Answer 1

Given that,

The table cloth are all 1.5 m long.

According to figure,

Let the side of table cloth is AC.

We need to calculate the length of the sides of the table cloth

Using pythagoras theorem

$(AC)^2=(AB)^2+(BC)^2$

${AC}=\sqrt{(AB)^2+(BC)^2}$

Where, AC = diagonal length

AB = BC = given length

Put the value into the formula

$AC=\sqrt{(1.5)^2+(1.5)^2}$

$AC=2.12\ m$

Hence, The length of the sides of the tablecloth is 2.12 m.
