A rectangular wooden piece of length 12m and length 6m is cut into 4 equal pieces. Find the area of one of the pieces.
Kindly answer this question with full steps
Answers
Answer:
18cm
Step-by-step explanation:
area of 1 piece = area of whole // by 4
area = l * b
area of total= l * b=12*6
=72
area of 1 piece = total area / by 4 = 72/4
=18cm
The area of 1 piece = 18cm
Answer:
Mathematics NCERT Grade 6, Chapter 10: Mensuration- This chapter will cover all the concepts of Perimeter and Area.
Perimeter is the distance covered along the boundary forming a closed figure when you go around the figure once.
The amount of surface enclosed by a closed figure is called its area.
Figures in which all sides and angles are equal are called regular closed figures.
The first part of the chapter covers the following topics:
1. Perimeter of a rectangle = 2 × (length + breadth)
2. Perimeter of square = 4 × length of a side
3. Perimeter of an equilateral triangle = 3 × length of a side
Next part of the chapter emphasises on area.
The first method explained is Calculation of area by counting squares.
To calculate the area of a figure using a squared paper, the following conventions are adopted:
(a) The area of one full square is taken as 1 sq unit. If it is a centimetre square sheet, then area of one full square will be 1 sq cm.
(b) Ignore portions of the area that are less than half a square.
(c) If more than half a square is in a region. Count it as one square.
(d) If exactly half the square is counted, take its area as 1/2 sq units.
