Question

Length is 4 times the breadth
I am a rectangle
breadth x
My perimeter is 70 cm
perimeter of the rectangle
2(x+
x ) = 70
(using formula)
2x
x = 70
x = 70
X =
breadth of rectangle
cm and
length of rectangle
cm​

Answer 1

Step-by-step explanation:

breadth =x

so,length=4x

perimeter=2(length+breadth)=70

=> 2(4x+x)=70

=> 10x=70

=> x=70/ 10

=> x=7

so breadth of the rectangle is 7 cm

and length is 7×4 cm=28 cm

Answer 2

Answer:

breadth = 7 & length = 28

Step-by-step explanation:

we know:

The perimeter of a rectangle is the total sum of all the sides of the rectangle.

so,

2( l + b) = perimeter of a rectangle

here, breadth is x, then length is 4x

2( 4x + x ) = 70

=> 8x + 2x = 70

=> 10x = 70

=> x = 70 = 7

10

hence, breadth of the rectangle is 7 (units). So, length of the rectangle is 4 × 7 = 28 (units).

I hope this helps you
