Oh, dude, it's like super simple math. The area of a rectangle is just the length times the width, so for this one, it's 3m x 12m which equals 36 square meters. Like, no big deal, just basic math stuff.

Well, darling, to find the area of a rectangle, you just multiply the length by the width. So, in this case, 3m x 12m gives you a snazzy area of 36 square meters. Voilà, math made fabulous!
The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length is 12m and the width is 3m. Therefore, the perimeter would be 2(12m) + 2(3m) = 24m + 6m = 30m.
Well, honey, to find the perimeter of a rectangle, you add up all the sides. So, for your rectangle with sides of 12m and 8m, you simply add 12 + 12 + 8 + 8 to get a perimeter of 40 meters. Voila!
3 x 7 sq m
6 Meter x 3 Meter = 18 m2
339.29 m3 to two decimal places.
