Question

the area of a rectangle is 4900 square m if breadth is 140 metre then what will be the length​

Answer 1

$\large{\underline{\underline{\mathfrak{\sf{\green{Answer-}}}}}}$

$\large{\underline{\boxed{\mathfrak{\blue{\sf{Length\:of\:rectangle=35\:m}}}}}}$

$\large{\underline{\underline{\mathfrak{\sf{\green{Explanation-}}}}}}$

$\orange{\boxed{\pink{\underline{\red{\mathfrak{Given-}}}}}}$

• Area of rectangle = 4900 m²
• Breadth of rectangle = 140 m

$\orange{\boxed{\pink{\underline{\red{\mathfrak{To\:find-}}}}}}$

• Length of rectangle

$\orange{\boxed{\pink{\underline{\red{\mathfrak{Figure-}}}}}}$

$\setlength{\unitlength}{2cm}\begin{picture}(16,4)\thicklines\put(8,3){\circle*{0.1}}\put(7.8,3){\large{D}}\put(7.2,2){\mathsf{\large{?m}}}\put(8,1){\circle*{0.1}}\put(7.8,1){\large{A}}\put(9.3,0.8){\mathsf{\large{140m}}}\put(11.1,1){\large{B}}\put(8,1){\line(1,0){3}}\put(11,1,){\circle*{0.1}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){3}}\put(11,3){\circle*{0.1}}\put(11.1,3){\large{C}}\end{picture}$

$\orange{\boxed{\pink{\underline{\red{\mathfrak{Formula\:used-}}}}}}$

• Area of rectangle = Length × Breadth

$\orange{\boxed{\pink{\underline{\red{\mathfrak{Solution-}}}}}}$

We know that,

Area of rectangle = Length × Breadth

★ Putting the given values

$\implies$ 4900 = Length × 140

$\implies$ Length = $\cancel{\dfrac{4900}{140}}$

$\large{\underline{\boxed{\mathfrak{\blue{\sf{Length\:of\:rectangle=35\:m}}}}}}$

Answer 2

$\huge\bold\pink{ANSWER}$

To find :

Length of the rectangle

We know :

Area of rectangle = $length \times breadth$

Solution :

$4900 \: {m}^{2} = l \times 140 \: m$

$l = \frac{4900}{140}$

$\boxed{l = 35m}$
