Question

The area of a rectangle is same as the area if a square .the length of the rectangle is 80cm and the breadth is 20cm.find the side of square
​

Answer 1

Step-by-step explanation:

Area of rectangle = length × breadth

= 80cm × 20cm

= 1600

if the area of rectangle is 1600 , so the area of square will be 1600

To , find the side of square ,

Area of square = side × side

1600 = 2side

1600/2 = side

800 = side

Answer 2

${\bigstar}$GIVEN${\bigstar}$

RECTANGLE:

• Length = 80cm
• breadth = 20cm

${\bigstar}$TO FIND${\bigstar}$

• side of a square

${\bigstar}$SOLUTION${\bigstar}$

Given that

☞Area of the rectangle = Area of a square

☞Length × breadth = side × side

☞80 × 20 = side²

☞1600 = side²

☞side = $\sqrt{1600}$

☞side = $\sqrt{40 \times 40}$

☞$\boxed{\sf{ side = 40cm }}$

hence ,

the side of the square = 40cm

RECTANGLE:

⇰perimeter = 2(l+b) units

⇰area = length × breadth sq.units

SQUARE:

⇰perimeter = 4a units

⇰area = a²sq.units
