Answer» Answer: 54 cm Step-by-step explanation: BREADTH = 12 cm PERIMETER = 54 cm Step-by-step explanation: Area of rectangle = length × breadth 180 = 15 × breadth breadth = 180÷15 breadth = 12 cm Perimeter of rectangle = 2 ( l + b) = 2 ( 15 + 12 ) = 2 ( 27 ) = 54 cm

(b) The area of a rectangle is 180 cm2 and its length is 15 cm. Find its breadthand perimeter.

Answer»

BREADTH = 12 cm PERIMETER = 54 cm

Step-by-step explanation:

Area of rectangle = length × breadth

180 = 15 × breadth

breadth = 180÷15

breadth = 12 cm

Perimeter of rectangle = 2 ( l + b)

= 2 ( 15 + 12 )

= 2 ( 27 )

= 54 cm
