Question

the area of a rectangle is 180m square. if its length is 18m, find it's breadth and perimeter​

Answer 1

Answer:

$area \: of \: rectangle = length \times breadth$

$180 = 18 \times breadth$

$\frac{180}{18} = breadth$

$breadth = 10m$

$perimeter \: of \: rectangle = 2 \times l + b$

$perimeter = 2 \times 10 + 18$

$perimeter = 2 \times 28$

$perimeter = 56$

Answer 2

AnswEr-:

• $\boxed {\mathrm{ Breadth \: of \: Rectangle\: = 10 m }}$
• $\boxed {\mathrm{Perimeter \: of \: Rectangle\: = 56 m }}$

Explanation-:

• $\mathrm{Given-:}$

• The area of a rectangle is 180 m².

• The length of Rectangle is 18 m .

• $\mathrm{To\:Find-:}$

• The breadth and Perimeter of Rectangle.

$\dag{\mathrm{Solution\:of\:Question\:-:}}$

• $\underline{\boxed{\star{\sf{\blue{ Area_{(Rectangle)}  \: = \: Length \times Breadth sq.\:units}}}}}$

Here ,

• The area of a rectangle is 180 m².
• The length of Rectangle is 18 m .

• The Breadth of Rectangle is ??

Now, By putting known Values in Formula-:

• $\longrightarrow {\mathrm{18 \times Breadth = 180m^{2}}}$

• $\longrightarrow {\mathrm{ Breadth = \dfrac{\cancel {180}}{\cancel{18}}}}$

• $\longrightarrow {\mathrm{ Breadth = 10 m }}$

Therefore,

• $\boxed {\mathrm{ Breadth \: of \: Rectangle\: = 10 m }}$

______________________________________

As we know that,

• $\underline{\boxed{\star{\sf{\blue{ Perimeter_{(Rectangle)}  \: = \:2( Length + Breadth) \:units}}}}}$

Here ,

• The length of Rectangle is 18 m .

• The Breadth of Rectangle is 10 m

Now, By putting known Values in Formula-:

• $\longrightarrow {\mathrm{Perimeter_{Rectangle}= 2(18+10) }}$

• $\longrightarrow {\mathrm{Perimeter_{Rectangle}= 2(28) }}$

• $\longrightarrow {\mathrm{Perimeter_{Rectangle}= 56 m }}$

Therefore,

• $\boxed {\mathrm{Perimeter \: of \: Rectangle\: = 56 m }}$

__________________________________________

Hence,

• $\boxed {\mathrm{ Breadth \: of \: Rectangle\: = 10 m }}$

• $\boxed {\mathrm{Perimeter \: of \: Rectangle\: = 56 m }}$
