Question

Find the area of the rectangle whose length is 5.7 cm and breath is 3 cm.

Answer 1

Hint: In order to solve this problem, we must choose the formula of area of the rectangle along with the proper understanding of properties and dimensions of the rectangle that is being provided in the question.

Complete step-by-step answer:
We know that

A rectangle is a 2-dimensional shape/polygon having four sides, four vertices, and four right angles. The two opposite sides in the rectangle are equal and parallel to each other. The area of a rectangle is the space covered by the shape which will be equal to multiplication of its length and breadth.
Alternatively,
the space within the perimeter of the rectangle is the area of a rectangle = length×breadth ${\text{uni}}{{\text{t}}^2}$

In question it is given that the length of the rectangle is 5.7cm and the breadth of the rectangle is 3cm.

Therefore, the area of the rectangle is length × breadth =5.7×3
= 17.1 ${\text{c}}{{\text{m}}^2}$

Note- Whenever we face such types of problems we have to remember the formula of area of rectangle which is stated above, then using this formula calculate the area of the given rectangle and simplify then we will get our required answer.
