Question

The area of a square is equal to the area of a rectangle of length 8cm and breadth 2cm what is the side of the square

Answer 1

Answer:

4

Step-by-step explanation:

area of rectangle is length *breadth

8*2=16

16/4=4

Answer 2

Answer:

The area of the square is area of the rectangle

The sides of rectangle are 8cm and 2cm

The formula for area of a rectangle is:

Area= length x breath

putting values in the formula we get

area1= 8 x 2

area1= 16 cm^2

The formula for area of a square is:

Area= side x side

area2= (side)^2

Since the area of the square and the  rectangle are equal we can equate area1 and area 2

we get,

16= (side)^2

side = root(16)

side= 4cm

The side of the square is equal to 4cm
