Find the area of rectangle with sides 2 5/6 and 4 4/7

g100num [7]

<h3>Given :</h3>

Length = $\sf2\dfrac{5}{6}$ cm.
Breadth = $\sf4\dfrac{4}{7}$ cm.

The area of rectangle.

<h3>Solution :</h3>

Area of rectangle = Length × Breadth

$\sf=2\dfrac{5}{6}\times4\dfrac{4}{7}$

$\sf=\dfrac{17}{6}\times\dfrac{25}{7}$

$\sf=\dfrac{17\times25}{6\times7}$

$\sf=\dfrac{425}{42}$

<h3>Area of rectangle is 425/42 cm².</h3>

An arithmetic sequence a starts 2, 5, . .

Whitepunk [10]

Answer:

Tn = 3n-1

T6 = 17

Step-by-step explanation:

Given the arithmetic sequence;

2, 5...

first term a = 2

Common difference d = 5-2 = 3

nth term of an AP is expressed as Tn = a + (n-1)d

Tn = 2 + (n-1)(3)

Tn = 2 + 3n-3

Tn = 3n-1

Get the 6th term

T6 = 3(6)-1

T6 = 18-1

T6 = 17

Hence the 6th term of the sequence is 17
