Important Questions ,worksheet for Class 6 Maths mensuration


Answer
(1)
These are straight forward question using the below formula of perimeter of rectangle,triangle,square
Perimeter of a rectangle = $2 \times (length + breadth)$
Perimeter of a square = $4 \times \text {length of its side}$
Perimeter of an equilateral triangle = $3 \times \text{length of a side}$
Perimeter of an triangle = $\text {sum of the lenght of the sides}$
(a) 30 cm
(b) 24 cm
(c) 11cm
(d) 40 cm
(e) 42 cm
(f) 39 cm
(g) 48 cm
(h) 25 cm
(2)
(a) 10 cm as third side= Perimeter - sum of the other two sides
(b) 10 cm as side of square = perimeter /4
(c) 30 cm as side of equilateral triangle = Perimeter/3
(d) 5 cm as Lenght + breadth = Perimter/2
(3) As Perimeter of a rectangle = $2 \times (length + breadth)$
Perimeter=302 m
(4) Distance= $10 \times Perimeter$
Now perimeter = 2(50+20) = 140m
Therefore,Distance= 1400m
(5) Distance= $3 \times Perimeter$
Now perimeter = 4*60 = 240m
Therefore,Distance= 720 m
(6) Pentagon has five equals sides So perimeter =$5 \times \text{lenght of the side} = 5 \times 6=30 cm$
(7) 100 m
(8) Area of rectangle is given by =$L \times B$
(a) 28 sq cm
(b) 42 sq m
(c) 11 sq m
(d) .2 sq m

(9) Area of square is given by =$side \times side$
(a) 121 sq cm
(b) 625 sq cm
(c) 144 sq m

(10) Area of the floor = Lenght × width= 12 sq m
Area of single tile=.5 × .5 = .25 sq m
Number of times required= 12 /.25 = 48

(11) Here we need to convert both the lenght and width into same unit
So ,lenght = 2 m
Width=1m 25 cm=1.25 m
Area= 2 × 1.25 = 2.5 sq m

(12) L=4 m
W=3 m 50 cm =3.5 m
Area of carpet = 4 * 3.5 = 14 sq m

(13) Area= 300 sq m
length =50 m
Area = Lenght × width= 50 × width
Therefore,
50 × width =300
width= 6 m

(14) Splitting the figure as below
Important Questions ,worksheet for Class 6 Maths mensuration
Area of the figure = Area AJIY + Area YWCB + Area DWUE + Area FUHG.
Area A J I Y = A J * J I = 3 * 3 = 9
Now, B Y = A B - Y A = 4 - 3 = 1
So, Area Y W C B = B Y * B C = 1 * 2 = 2
Next, D W = D C + C W = 2 + 1 = 3
Therefore, area D W U E = D W * D E = 3 * 3 = 9
Similarly, U H = I H - I U = 4 - 2 = 2
G H = F U and F U = E U + F E
= D W + F E = 3 + 1= 4
Area F U H G = U H * G H = 2 * 4 = 8
Therefore, the area of the figure = 9 + 2 + 9 + 8
= 28sq units

(15) Side of Hexagon = perimeter / 6 = 30/6 =5 cm
Now Perimeter of the given figure= 10 × side = 50 cm
