this is Friday's masks video so we are working on pages 114 and 142 in your math work a square field has a perimeter of 44 so the distance around the square is 44 find the length of one side of the when you know the perimeter and it's a flare so you know all four sides are the same all four sides are equal if you want to get one of the side you take the perimeter and divided by 4 the range of 44 / 4.5 is 11 meters if you wanted to check you would do 11 plus 11 * 44 perimeter of a rectangular town is 32 MI it does say that the West is five miles we need to find the perimeter we are adding all the sides we know that there are four sides on a rectangle so you remember me doing this for some other phones would like to put the spaces for where the numbers would go if I'm fine. Forsyth together getting 32 for this problem I know the whip I know this is fine and because of the rectangle I know this is also and then what's unknown is the lent these two numbers what I do know is that whatever this site is this side is the same it's a rectangle two opposite sides are so whenever number goes. Amber has to go here 5 to 5 is 10 32 take away the size we already know what we know is that the length plus the length equals 32 - 10 going to take away the way bus 22 what number added to itself would equal 20 another way divided by 2 and it is 11 * 11 + 11 would equal 22 miles numbers together 5 + 5 + 11 + 11 21 + 11 is 11 miles continue 142 perimeter of a rectangle is 24 cm in length is 9 cm you're out the missing so against weed we also know that already has nine so I can put that for two of the sides are unknown 9 + -18 what we know is that the and they have to be the same number so what number added to itself would equals 6 or another words what is 6 / and that would be 3 * 3 + 3 is 6 there for we know the width must be 3 centimeters we can check it by adding it together again so 4/9 + 9 + 18 21 + 3 is what is 3 centimeters the perimeter of a rectangular Garden is 18 yards it's length is 6 yards find its width similar problem we're given the perimeter is 80 is with means the other side across from it is we don't know the way weather for science for science we know that you lent are six we don't know the to its 6 + 6 is 12 so we're going to take away but we already know relax with six. State a problem or that was true remember to divide 6 by 2. so we can assume that this is a perimeter up again so if the width is 3 we do 3 + 3 + 6 + 6 equal 18 3 + 3 + 6/6 + 6 + 12 + 12 + 688 is 3 yards that's it for
