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 ALGEBROS💡 So today on MATHSPEDIA A+🧠we shall discuss and focus on Wait for it 5 algebatic terms After the lesson if there is a part you don't understand feel free to comment Fig 1. So let's begin 1. X×X×X= x3 That is if X multiplies itself 3 times It becomes X raised to the power 3 The same way if you have something like 3x ×3x ×3x You'll get 27x3 That is 27x raised to the power 3 The same way if 3 multiplies itself 2 times it will give you 3 raised to the power 2 Fig 2. 2. X+X+X=3X Here we see that if you add numbers 3 times to itself it will not give u the same answer as if you multiply it 3 times to itself So X+X+X is not equal to X×X×X The same way 3+3+3 is not equal to 3×3×3 Fig 3. 3. Y 1 = Y Fig 4. 4. Y0 = 1 Fig 5. Eg. a 1 = a. Any number raised to the power of one equals the number itself. For any number a, except 0, a0 = 1 . Any number raised to the power of zero, except zero, equals one . 5. X×X ≠ X+X To solve x multiplied by x , try to observe
