Question

Find the length of side of the square,whose area is equal to the area of a rectangle with sides 240m 70m

Answer 1

Answer:

Side of square =  $20 \sqrt{42}$

Step-by-step explanation:

We have been given that the sides of a rectangle are 240m and 70m.

We also know that the area of a rectangle is length x breadth.

We also know that the area of a square is Side x Side.

Acc. to Question:-

Side x Side = 240 x 70

Side² = 16800m²

Side = $\sqrt{16800}$

Side = $\sqrt{16800}$

Side = $\sqrt{2\times2\times2\times2\times2\times3\times5\times5\times7}$

Side = $20 \sqrt{42}$

So, the side of the square is $20 \sqrt{42}$ m !

Answer 2

Answer:

first we will find area of rectangle

Step-by-step explanation:

area of rectangle = l×b

=240×70

=16800

now according to question area of rectangle is equal to area of square

area of square =a^2

16800=a^2

a=under root 16800

a=20 under root 42
