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 Wait for it  5  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. Multiplication of two digit number by 11                           -1- 35 × 11 Step 1- Add both digits of the two digit number 3 + 5 = 8 Step 2- Place the result in between both digits 3_8_5 = 385 Fig 2. -2- 78 × 11= 858 Step 1 - Add both digits of the two digit number 7+8= 1 5 Step 2- Carry the one when the result is greater than nine 7+ 1= 8 Step 3- Place the result in between both digits  8_5_8=858 Fig 3. 2. Multiply by 9:       -1- 56 ×9= 504 Step 1- Multiply the number by 10: 56× 10 =560 Step 2- Subtract the original number from step 1 560 - 56= 504 Fig 4. 3. Multiply numbers between 11 and 19     -1- 14 ×18= 252 Step 1- Add the larger number to the rightmost digit of the other number 18 + 4=22 Step 2- Put a zero at the end of the...

Hello GREATMINDS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on  5  more Arithme-tricks😉 on squaring of some numbers After the lesson if there is a part you don't understand  feel free to comment Fig 1. So let's begin 1. Square numbers ending in 5            .1. 35 2  = 1225 Step 1- Multiply the first digit by the first digit plus one 3 ×(3+1)=12 Step 2- Write the number 25 next to the result from Step 1 12_ 25 Fig 2. 2. Square numbers between 10 and 19       .1.  14^2 = 196 Step 1-  Add the number to the ones digit 14+4=18 Step 2- Multiply the number from Step 1 by 10 18 × 10 =180 Step 3- Square the ones digit number  4^2 = 16 Step 4- Add Step 2 and 3 180+16=196 Fig 3.  3. Square numbers between 40 and 49 -1- 48^2= 2304 Step 1- Subtract the number from 50 50-48=2 Step 2- Subtract the result(from Step 1 ) from 25 25-2=23 Step 3- Square the result from Step 1 ( if the result is a single digit put a zero in front of it) 2^2=04 Step 4- Place the result from Step 3 ne...
