Question

Length and Area of rectangle is 20cm; 280cm², then what is it's breadth ?

Answer 1

20cm multiple 280cm2 right anser kyo hila dala na prank tha

Answer 2

Given:

• Length (L) = 20cm
• Area (A) = 280cm²

To Find:

• It's Breadth.

Solution:

Here, The Given length is 20cm ; Area = 280cm² ! And we have to find the breadth so, Let the breadth be ${x}$

⠀⠀$\longrightarrow$ Area of Rectangle = 280cm²

⠀⠀$\longrightarrow$ Length of Rectangle = 20cm

⠀⠀$\longrightarrow$ Breadth of Rectangle = ${x}$

Now,

$\begin{gathered} :\implies\sf {~Area ~of \: Rectangle = {280cm}^{2} }\\\\\\ \: :\implies \sf { Length \times Breadth = {280cm}^{2}}\\\\\\ :\implies\sf{ 20cm \times b = {280cm}^{2} } \\ \\ \\ \: :\implies\sf{~b \: = \dfrac{Area}{Length} } \\\\\\ \: :\implies\sf{~b = \dfrac{280}{20} } \\ \\ \\ \: :\implies{\underline{\boxed{\frak{\pink{~14cm~}}}}}\end{gathered}$

$\therefore {\underline {\frak{\gray{~The ~breadth ~of ~rectangle ~is~14cm}}}}$

__________________________________

Let us Verify it too:

• Area = 280cm²
• Length = 20cm
• Breadth = 14cm

Area of Rectangle = Length × Breadth

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀= 20 × 14

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 280cm²

Hence, Done !
