Question

the length and breadth of some rectangles aregiven. find their perimeter using the formula (a) l=3.5m, b=3m​

Answer 1

Answer :

16

Explaination :

The formula for perimeter of rectangle is 2*Length+Breadth

= 2*3.5m+3m

= 2*6.5

=13

Answer 2

★ Answer :-

Perimeter of the required rectangle ↬ 13m.

Step by step explanation :-

Given :-

• Length (l) = 3.5 m
• Breadth (b) = 3 m

Have to Find :-

• Find the $perimeter$ .

Solution :-

As we all know the perimeter of rectangle .

Perimeter = 2 ( length + breadth )

Now , putting up the values.

↬ p = 2 ( 3.5 + 3 )

↬ p = 2 ( 6.5 )

↬ p = 13 m

{ converting into cm }

↬ p = 1300 cm

Important Formulas :-

↬ Perimeter of Rectangle = 2( L + B )

↬ Perimeter of square = 4 × Side

↬ Perimeter of triangle = AB + BC + CA

↬ Area of Rectangle = L × B

↬ Area of Square = ( side ) ²

↬ Area of Rhombus = Product of Diagonal/2.

↬ Area of Parallelogram = Base × Height.

↬ Area of triangle = ½ × base × height .
