Question

A rectangle of sides 8cm and 10 cm is divided into four equal rectangles what is the perimeter of each small rectangle​

Answer 1

When we divide the big rectangle into 4 equal rectangles, the lengths and breadths of the 4 new rectangles will be 1/2 of the big rectangle

So, perimeter of new rectangle =

2[(l+b)/2]
= l+b

= 10 + 8

= 18

So, the perimeter of each new rectangle is 18 cm

Hope this helped!

Answer 2

Answer: 18 cm is the perimeter of each small rectangle.

Given: We are given that there is a rectangle with sides 8cm and 10cm.

To Find: We need to find the perimeter of each small rectangle if the given rectangle is divided into 4 equal rectangles.

Step-by-Step Explanation: It is given that the original rectangle is divided into 4 equal parts. Therefore, the length and width of the rectangle reduce to half of their original value. I have shown this in the explanation figure attached with this answer.

Step 1: So, in the figure we can see that the length of each small rectangle becomes 5cm and the width of the rectangle becomes 4cm.

We know that the formula for perimeter of a rectangle is: $2(l+b)$ where l is the length of the rectangle and b is the width of the rectangle.

Calculating perimeter: $2(l+b)$

                                   = 2(5+4)  ( l=5cm and b = 4cm)

                                    = 18cm
