Answer 2

Question :-

Area of a rectangle is √90 cm². Breadth is 3 cm. Find its length and perimeter.

Answer :-

Given :-

• Area = √90 cm²
• Breadth = 3 cm

To Find :-

• Length
• Perimeter

Solution :-

Area = Length × Breadth

√90 cm² = 3 × length

L = √90/3

L = 3√10/3

L = √10 cm = 3.16 cm

Length = 3.16 cm

Perimeter = 2 ( l + b )

= 2 ( 3.16 + 3 )

= 2 ( 6.16 )

= 12.32

Perimeter = 12.32 cm
