1.	If the length of a rectangle is twice its breadth and its perimeter is 120 m then what is length
Answer» Breadth = 20 cm Length = 40 cm he AREA of rectangle is 800 sq.cm Step-by-step EXPLANATION: Let the breadth of rectangle be x We are given that The length of a rectangle is twice its breadth. So, length = 2x Perimeter of rectangle = 2(Length+Breadth)=2(2x+x)=6x2(Length+Breadth)=2(2x+x)=6x We are given that The perimeter of the rectangle is 120 cm. So, 6x=1206x=120 x=20x=20 So, Breadth = 20 cm Length =2x = 2*20 = 40 cm Area of rectangle = Length \times Breadth = 40 \times 20 = 800 cm^2Length×Breadth=40×20=800cm2 Hence The area of rectangle is 800 sq.cm

If the length of a rectangle is twice its breadth and its perimeter is 120 m then what is length

Answer»

Breadth = 20 cm

Length = 40 cm

he AREA of rectangle is 800 sq.cm

Step-by-step EXPLANATION:

Let the breadth of rectangle be x

We are given that The length of a rectangle is twice its breadth.

So, length = 2x

Perimeter of rectangle = 2(Length+Breadth)=2(2x+x)=6x2(Length+Breadth)=2(2x+x)=6x

We are given that The perimeter of the rectangle is 120 cm.

So, 6x=1206x=120

x=20x=20

So, Breadth = 20 cm

Length =2x = 2*20 = 40 cm

Area of rectangle = Length \times Breadth = 40 \times 20 = 800 cm^2Length×Breadth=40×20=800cm2

Hence The area of rectangle is 800 sq.cm
