So today on MATHSPEDIA we shall discuss some elementry Formulae to find the Area and perimeter of 5 shapes After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's start 1a.  Area of a square = L×L= L square Where L= Length This is so because a square has all it's sides and angles equal 1b.  Perimeter of a square = L+L+L+L =4×L =4L Fig 2. 2a.  Area of a rectangle= L×B(L=length,B= breadth) 2b.  Perimeter of a rectangle= L+L+B+B                 =2L+2B                                               =2(L+B) 3a.  Area of a right angled triangle= 1/2×b×h (b=base, h=height) 3b.  Perimeter of a triangle= Sides a+b+c Fig 3. 4.  The area and circumference of a circle will be shown below👇: Fig 4. This image above👆 explains the circumference of a circle  Fig 5. The image above👆 shows the area and circumference of a circle. Fig 6. The image...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on multiplication of some digits After the lesson if there is a part you don't understand  feel free to comment Fig 1. So let's begin  1. Multipy by 5         -1- 1234×5 = 6170 Step 1- Divide the number by 2 1234 /2 =617 Step 2- Multiply the result from Step 1 by 10 617×10 = 6170 Fig 2. 2. Multiply by 6     -1- 16×6 = 96 6= 5+1= (10/2)+1 Step 1 - Divide the number by 2 16 /2= 8 Step 2 - Multiply the number from Step 1 by 10 8×10 = 80 Step 3- Multiply the number by 1 16×1=16 Step 4- Add Step 2 and 3 80+16 = 96 Fig 3. 3. Multiply by 20 -1- 36×20 = 720 Step 1- Multiply the number by 2 36 × 2= 72 Step 2- Multiply the number from Step 1 by 10 72×10= 720 Fig 4. 4. Multiply by 25 -1- 18×25=450 Step 1- Divide the number by 4 18/4 = 4.5 Step 2- Multiply the number from Step 1 by 100 4.5×100 = 450 Fig 5. 5. Multiply by 50 -1- 18×50 =900 Step 1- Divide the number by 2 18/2= 9 Step 2- Mult...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss some more elementry formulae to find the Area/volume and perimeter of 5 more shapes After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's begin 1a. Area of a parallelogram  = b×h (b=base, h=height) 1b. Perimeter of a parallelogram = Sides(a+a+b+b) =2a+2b =2(a+b) Fig 2. 2a. Area of a rhombus= There area several ways of finding the area of a rhombus 2ai. Area of rhombus with length of diagonals= (d1*d2)/2, * = × Fig 3. 2aii. Area of a rhombus with base and height = b×h Fig 4. 2b. Perimeter of a rhombus = sum of the lenght of the rhombus =l+l+l+l =4L Fig 5. 3a. Area of a kite when both diagonals are given= (d1×d2)/2 Fig 6. 3b. Perimeter of a kite = a+a+b+b = 2a+2b =2(a+b) Fig 7. 4a. Volume of a sphere = 4/3Ï€r3 4b. Surface area of sphere =4Ï€r² Fig 8. 5. Volume of a Cylinder = Ï€r²h Fig 9. That's all for the day GREATMINDS💡 JOIN US NEXT TIME FOR WAIT FOR IT MORE SHAPE...
