2️⃣ 48 cm
3️⃣ 24 cm
4️⃣ 32 cm

Answer 1

Answer:

3

Step-by-step explanation:

hope it will helpful to you

taking 3 and 2 as x

perimeter of rectangle is l×b=3x:2x=80

by doing the problem we get 24 cm

Answer 2

Answer:

3. 24cm

Step-by-step explanation:

Concept= Perimeter of Rectangle

Given= The Perimeter of Rectangle and Length in Ratio

To find= Actual length of Rectangle

Explanation=

We have been given the perimeter of rectangle and the sides of rectangle in ratio.

Perimeter= 80cm

Sides = 3:2

Let the Sides be 3x and 2x

Perimeter of rectangle is twice the sum of sides of rectangle

2(length + breadth)

Length = 3x

Breadth = 2x.

Therefore ,

80= 2(3x+2x)

40= 5x

x=8cm

Length of sides are

3x= 3*8=24cm

2x= 2*8=16cm

Therefore the length of sides are 24cm  and 16cm.

The length of Rectangle is 24cm.
