Question

the area of a rectangular land is 520 sq. unit if the breadth of a land is 20 unit then what will be its length​

Answer 1

Step-by-step explanation:

Area of rectangular land = 520 sq. unit

length × breadth = 520 sq. unit

length × 20 = 520

length = 520/20 = 26 unit

Answer 2

Solution :

$\bf{\red{\underline{\underline{\bf{Given\::}}}}}$

The area of a rectangle land is 520 sq. unit,if the breadth of a land is 20 unit.

$\bf{\red{\underline{\underline{\bf{To\:find\::}}}}}$

The length of the land.

$\bf{\red{\underline{\underline{\bf{Explanation\::}}}}}$

Let the length of the land be r unit

We know that formula of the area of rectangle :

$\bf{\boxed{\bf{Area\:of\:rectangle=Length\times breadth}}}}}}$

A/q

$\mapsto\sf{520=r\times 20}\\\\\\\mapsto\sf{r=\cancel{\dfrac{520}{20} }}\\\\\\\mapsto\sf{\orange{r=26\:unit}}$

Thus;

The land of the length is 26 unit.

$\boxed{\begin{minipage}{6 cm} Formulas of rectangle : \\ \\ \sf{Perimeter=2(Length+Breadth)}\\ \\ \sf{Area=Length * breadth }\\ \\ \sf{Diagonal = \sqrt{(length)^{2} +(Breadth)^{2} }} \end{minipage}}$
