Find the length and perimeter of a rectangle
120 cm2 and breadth = 8 cm.
a​

Answer 1

Answer:

area = 120 cm^2

breath = 8 cm

length = ?

area = length × breath

120  =  length × 8

length =  120 ÷ 8

length = 15

perimeter =  2×( length + breath )

                =  2 ( 15 + 8 )

               =   2 × 23

                =  46 cm

Answer 2

Answer:

Length of the rectangle = 15 cm

Perimeter of rectangle = 46 cm

Step-by-step explanation:

Area of rectangle = 120 sq. cm.

Breadth of rectangle = 8 cm.

Area of rectangle = length × breath

120 = length × 8

length = 120/8

length = 15

Therefore,

Length of the rectangle = 15 cm

Perimeter of rectangle = 2 ( length + breadth )

= 2 ( 15 + 8 )

= 2 × 23

= 46 cm

( Note: Write length as small 'l' while writing in the notebook in the formula steps )
