W.A.L.T: Area, Perimeter and Volume Yr 9/10
The pythagoras theorem can be hard when you first start but the easiest way to remember is doing a2 + b2 = c2.
so you times 12 x 12 and 16 x 16 witch are 144 and 256, then you add 256 to 144 witch equals 400 then you find the square root of 400 witch is 20! then you add 20 to 12 and 16 witch equals 48!
The difference between area and perimeter is that perimeter is + and area is x.
Next Step: complete volume.
