Question

If the length of rectangle is 45m , and area is 225 metre square,then find the breadth of rectangle please fast​

Answer 1

Answer:

5 is the breadth.

Step-by-step explanation:

Divide 225 with 45.

Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: SOLUTION \: \: } \mid}}}}}$

Given,

Length of the rectangle, l = 45 m

Area of the rectangle, A = 225 m²

To find :

Breadth of the rectangle, b = ?

We know that,

$\boxed{ \bold{ \: Area \: \: of \: \: a \: \: rectangle = Length \times Breadth \: }}$

Using this formula,

$\sf{Area = Length × Breadth} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf{\implies \: 225 \: m {}^{2} = 45 \: m \times b} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf{\implies \: b = \frac{225 \: m {}^{2} }{45 \: m}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf{\implies \: b = 5 \: m} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

∴ If the length of rectangle is 45 m , and area is 225 m² , then the breadth of rectangle = 5 m

➢ WHAT IS A RECTANGLE ?

⇴ A rectangle is a plane figure that has four right angles and four straight sides in which one pair of lines is longer than the other pair.

▪︎ According to Euclidean plane geometry, a rectangle can be defined as a quadrilateral with four right angles.

• A rectangle is a 2D shape figure in geometry having 4 sides and 4 corners.

• The opposite sides of a rectangle are parallel and have the same lengths.

• The measure of each the four angles of a rectangle is 90°.

• The sum of all the four angles of a rectangle is 360°.

• A rectangle can have two diagonals of equal length.

• The diagonals of a rectangle bisect each other.

➥ AREA OF A RECTANGLE = LENGTH × BREADTH

➥ PERIMETER OF A RECTANGLE = 2 (LENGTH + BREADTH)

➥ LENGTH OF DIAGONAL OF A RECTANGLE = √ (LENGTH)² + (BREADTH)²
