Question

A rectangle is 80 cm long and 20 CM broad find the side of a square whose area is equal to the area of this rectangle

Answer 1

Answer:

Hence the side is of 200

Step-by-step explanation:

Area of rectangle = 80×20= 1600

Area of rectangle = area of square

Area of square = side sq.

x sq. . = 1600

1600/2

=800/4

=200

Answer 2

$\Large{\textbf{\underline{\underline{According\;to\;the\;Question}}}}$

Given

Breadth of Rectangle = 20 m

Length of Rectangle = 80 m

As we know that,

${\boxed{\sf\:{Area\;of\;Rectangle = Length\times Breadth}}}$

Area of Rectangle = 80m × 20m

Area of Rectangle = 1600m²

Now

Given,

${\boxed{\sf\:{Area\;of\;Rectangle = Area\;of\; Square}}}$

Area of Square = 1600m²

As we know that,

Area of Square = (Side)²

1600 = (a)²

√1600 = a

40 = a

Side = 40m

Hence we get,

$\textbf{\underline{Side\;of\;Square = 40m}}$
