Question

Find the length of a rectangle whose area is 104 square cm and breadth is 8cm

Answer 1

$\bold{Answer :-}$

A rectangle is a plane and closed figure with four sides and angles

To find area we use the formula, l×b

According to the question,

• Area = 104 sq.cm

• breadth= 8cm

From the formula, to find length, we divide area and breadth

length = area/breath

=104/8

=13

so, length is 13 cm

Answer 2

$\begin{lgathered} \red{\bf{Given}}\begin{cases} \sf \: area \: of \: rectangle =104 {cm}^{2} \\ \sf breadth = 8cm \\ \sf \: length =?\end{cases}\end{lgathered}$

$\Large\bold\star\underline{\underline\textbf{Formula\:used}}$

$\green{\boxed{ \bf Area_{Rectangle}= Length * Breadth }}$

Putting Values we get,,,

$\red\leadsto \: 104 = 8 \times length \\ \\ \red\leadsto \: length \: = \frac{104}{8} \\ \\ \red\leadsto \: \pink{\large\boxed{\boxed{\bold{length = 13cm}}}}$

1) Each of the interior angles of a rectangle is 90°.

2) The diagonals of a rectangle bisect each other.

3) The opposite sides of a rectangle are parallel.

4) The opposite sides of a rectangle are equal.

5) A rectangle whose side lengths are a and b has area = a×b×sin90° = a×b

6) A rectangle whose side lengths are a a and b b has perimeter 2(a + b)...

7) The length of each diagonal of a rectangle whose side lengths are a and b is √(a²+b²) ..
