Let’s solve the question!
- Area = Side 2
-
=X
-
=cm 2
- Area = B X H
-
=X
-
=cm 2
- Area = B X H
-
=X
-
=cm 2
- Area = ((B1=a) + (B2=b)) X H ÷ 2
-
=(+)X÷
-
=(X)÷
-
=÷
-
=cm 2
- Area = (B X H) ÷ 2
-
=(X)÷
-
=÷
-
=cm 2
- Diameter = 2 X r (Radius)
-
=X
-
=cm 2
- A cube has 6 faces. Find an area of one face.
- Multiply the area with 6
- Area = 6 X Side 2
-
=XX
-
=cm 2
- Perimeter = 4 x Side
-
=X
-
=cm
- The rectangle has 2 equal bases and heights.
- Perimeter = (2 X B) + (2 X H)
-
=X+X
-
=+
-
=cm
- The rectangle has 2 equal bases and heights.
- Perimeter = 2 X (B + H)
-
=X+
-
=X
-
=cm
- Perimeter = a + b + c + d
-
=+++
-
=cm
- Perimeter = a + b + c
-
=++
-
=cm
- Area = π (3.14) X r2 (Radius)
-
=XX
-
=cm
- A cube has 12 edges.
- Multiply the edges with 12
- Perimeter = 12 X Edge
-
=X
-
=cm 2
