Question

The perineter of a rectangle is 600cm and length is 12 cm find the breadth and area

Answer 1

Answer :

Breadth = 288 cm

Area = 3456 cm²

Step-by-step explanation :

Let the breadth of the rectangle be x.

According to the question,

Perimeter of rectangle = 600 cm

⇒ 2 ( l + b ) = 600

⇒ 2 ( 12 + x ) = 600

⇒ 12 + x = 600 / 2

⇒ 12 + x = 300

⇒ x = 300 - 12

⇒ x = 288

Hence, the breadth of rectangle is 288 cm.

Area of rectangle = length × breadth

                            = 12 × 288

                            = 3456 cm²

Hence, the area of rectangle is 3456 cm²

Answer 2

let breadth be x.=288cm
area=12×288=3456cm^2
