Question

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

Answer 1

Answer:

20√42m

Step-by-step explanation:

let the length of the side of the square be x .

area of rectangle

=240×70 m

=16800 m2

It given that area of the square is equal to the area of the rectangle.

since area of the rectangle is 16800 m2

therefore ,area of the square =area of the rectangle=16800m2

therefore length

=>x×x=16800(since length square gives area in a square )

=>x2=16800

=>x=√16,800

therefore x =20√42m
