Question

The length of a rectangle is three times its breadth. If its perimeter is 64 cm, find the sides of the rectangle.​

Answer 1

Answer:

The sides of the rectangle are 24 cm and 8 cm

Step-by-step explanation:

Let the breadth of rectangle be x

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

So, Length = 3x

Perimeter = 2(l+b)=2(3x+x)=2(4x)=8x

We are given that the perimeter is 64 cm

So, 8x = 64

x=\frac{64}{8} = 8

8

64

=8

Length = 3x=3(8)=24 cm

So, the sides of the rectangle are 24 cm and 8 cm

Answer 2

breadth= x

length= 3x

perimeter =64cm

perimeter =2(L+b)

64=2(3x+x)

64=2(4x)

64/2=4x

32=4x

32/4=x

8=x

breadth=x=8

length=3x=3×8=24
