Question

The area of a rectangle is what​

Answer 1

Explanation.

♦ Area of Rectangle

• Length × Breadth

`\underline{ \rule{140pt}{4pt}}`

Additional Information :-

Area - Region occupied by figure is called area.

`\large \bf{ \mathfrak{{More \: Formulas \: \red{( Area)}}}}`

`\large \sf \leadsto \: triangle = (1)/(2) * bh`

`\large \sf \leadsto \: \: Rectangle \: = \: lb`

`\large \sf \leadsto \: \: Square \: = {s}^(2)`

`\large \sf \leadsto \: \: Parallelogram \: = \: bh`

`\large \sf \leadsto \: \: Rhombus \: = \: (1)/(2) * \: d1 * d2`

`\large \sf \leadsto \: \: Trapezium \: = (1)/(2) * (x + y) * h`

`\large \sf \leadsto \: \: Quadrilateral \: = \: (1)/(2) * d(h1 + h2)`

`\large \sf \leadsto \: Circle \: = {\pi \: r}^(2)`

`\large \sf \leadsto \: \: Equilateral \triangle \: = ( √(3) )/(4) * {s}^(2)`

Answer 2

Answer:

The area of rectangle is Length × Breadth

Explanation:

You have already learnt that perimeters of plane figures and areas of squares and rectangles. Perimeter is the distance around a closed figure while area is the part of plane or reason occupied by the closed figure.

`\sf \: Squares \: and \: Rectangles`

Ananya and samira made pictures. Ananya made her picture on a rectangular sheet of length 60 cm and breadth 20 cm while samira made hers on a rectangular seat of length 40 cm and breadth 35 cm. Both these pictures have to be separately framed and laminated.

Who has to pay more for farming is the cost of farming is $3.00 per cm?

If the cost of lamination is $2.00 per cm², who has to pay more for lamination?

For finding the cost of farming, we need to find perimeter and then multiply it by the rate for farming. For finding the cost of lamination we need to find area and then multiply it by the rate of lamination.

Example:-

Find the area of the rectangle whose Length is 4 cm and breadth/width is 6 cm .

Answer:

The area of the rectangle is 24 cm²

Explanation:

Length of rectangle = 4 cm

Breadth of rectangle = 6 cm

`\bf \: Formula \: used`

`\sf \: Area_ { \{Rectangle \}} = Length × Breadth`

Now put values

`\sf \: Length = 4 cm`

`\sf \: Breadth = 6 cm`

`\sf \: Length × Breadth = 4 × 6 \: cm`

`\sf \implies 24 \: cm \ {}^(2)`

Always remember if we find area :-

After units like centimetres,metres we always put (²) on these units.

Like :- 26 cm², 56 m ²

In words = Twenty six centimetre square, Fifty six centimetre square

Required Answer :

The area of rectangle is 24 cm²

Additional informatioN

Perimeter

• Parallelogram = 2(Base + Height)
• Triangle = a + b + c
• Rectangle = 2(Length + Width)
• Square = 4×side
• Trapezoid = Base + Base + side + side
• Rhombus = 4 × side
• Hexagon = 6 × side

Area

• Square area formula: = side×side
• Rectangle area formula: = L × B
• Circle area formula: = πr²
• Circle sector area formula: = r² × angle / 2.
• Ellipse area formula: = Axis× Axis × π
• Trapezoid area formula: = (base + base) × h / 2.
• Area of a Triangle = A = ½ (b × h)
