Question

length and breath of rectangular field is 405 m and 80 m.find the length of each side of square whose area is equal to each other.​

Answer 1

$\\ \large\underline{ \underline{ \sf{ \red{given:} }}}$

• Length of rectangular field = 405m

• Breadth of rectangular field = 80m

• Area of rectangle = Area of square

$\\ \\ \large\underline{ \underline{ \sf{ \red{to \: find:} }}}$

• Side of Square.

$\\ \\ \large\underline{ \underline{ \sf{ \red{solution:} }}}$

$\\ \star \boxed{ \bf \:area \: of \: rectangle =l \times b}$

Here ,

• Length = 405m

• Breadth = 80m

➛ Area = 405 × 80

$\\ \therefore \: \sf \: area \: of \: rectangular \: field \: is \: 32400 {m}^{2}.$

Since , area of rectangle = area of square ,

➟ Area of square = 32400m².

$\\ \star \boxed{ \bf \:area \: of \: square = {side}^{2} }$

➛ 32400 = Side ²

➛ Side = √32400

➛ Side = 180m

Hence , side of the square having same area as that of rectangular field is 180m.
