Question

The perimeter of a rectangle of an area 650 cm. whose breadth is 13 cm,is​

Answer 1

Answer:

area = l×b

13 × x = 650

13x=650

x= 650÷13

50

perimeter = 2(l+b)

2(13+50)

2×63

126

Answer 2

Answer:

126cm

Step-by-step explanation:

Let the length of the rectangle be x

Breadth = 13cm

Area = 650cm²

Formula of area of a rectangle = l×b

∴ 650cm² = x × 13cm

⇒x = 650cm²/13cm

⇒x = 50cm

∴ The length of the rectangle is 50cm

Formula of perimeter of a rectangle = 2×(l + b)

                                                            = 2×(50 + 13)

                                                            = 2×63

                                                            = 126cm

Therefore, the perimeter of the rectangle is 126cm
