We're being asked to express the area or find the area and perimeter for the given rectangle.
00:05
So let's start with the area.
00:07
Remember, the formula to find the area of a rectangle is we have to multiply the length times the width.
00:13
So for this problem, our lane is four -thirds t, and our width is five aphs t.
00:18
So we just need to substitute these expressions into our formula.
00:22
So when we do that, we'll have a equals the length, which is four -thirds t, times the width, which is five -aifs -t.
00:30
Now, we need to multiply these expressions.
00:33
Remember, to do that, we're going to multiply the coefficients.
00:36
So we'll have four thirds times five paves, which is 20 over 24, and then we multiply t times t, which is t squared.
00:45
But remember, we can reduce 20 over 24 by divided by two.
00:49
So that will leave us with 10 over 12.
00:51
Actually, i'll take that back.
00:53
We can reduce by divided by four.
00:54
So that will leave us with 5, 6, t squared...
