Question

(1) A rectangular plot has a length of 28 m and a breadth of 22 m. Findthe perimeter of the plot.​

Answer 1

Answer:

perimeter = 2 × ( l + b )

= 2 × ( 28 + 22 )

= 2 × 50

= 100 meter square

Answer 2

$\LARGE \rm{ \underline{ \underline \purple{Clarification :}}}$

In order to find the perimeter of the plot, we will use the formula 2(l+b), then we will put the value of length that is 28m and then we will put the value of breadth that is 22m, then we will add 28+22 m then lastly we will multiply the answer with 2 and that's our perimeter of the plot!

Required Answer :-

Length $\dashrightarrow$ 28m

Breadth $\dashrightarrow$ 22m

Perimeter of rectangle $\dashrightarrow$ 2(l+b)

$\longmapsto \sf{2(28 + 22m)}$

$\sf{ = 2(50m)}$

$\sf{ \red{ \underline{ = 100m}}}$

$\sf{ \therefore \: the \: perimeter \: of \: the \: plot \: is \: 100m.}$

More to know :

• The length of the boundary of a closed figure is called a Perimeter.

• The amount of a surface enclosed by a closed figure is called Area.

• Perimeter of a square → 4 × side

• Perimeter of a rectangle → 2 × (Length × breadth)

• Area of square → side × side

• Area of rectangle → Length × breadth
