Question

A rectangle is 1.7 inches wide by 1.2 inches long. What is its perimeter?

Answer 1

Answer:

5.8

Step-by-step explanation:

1.7*2= 3.4

1.2*2= 2.4

3.4+2.4= 5.8

Answer 2

A rectangle is 1.7 inches wide by 1.2 inches long. Then its perimeter is 5.8 inches

Solution:

We have been given a Rectangle whose length is L = 1.2 inches and breadth is B = 1.7 inches    

The perimeter of the rectangle is given as:

$\text { Perimeter }=\mathrm{P}=2 \times(\mathrm{L}+\mathrm{B})$

Where P means the perimeter

L, B are the lengths and breadth of the rectangle respectively

By substituting the values we get,

$\begin{array}{l}{P=2 \times(1.2+1.7)} \\\\ {P=2 \times(2.9)} \\\\ {P=5.8 \text { inches }}\end{array}$

So, the Perimeter of the rectangle is 5.8 inches
