Ah, what a lovely question! To find the perimeter of a rectangle, you simply add up all the sides. So for your rectangle that is 5 meters by 4 meters, you would add 5 + 5 + 4 + 4 to get a perimeter of 18 meters. Just imagine that rectangle surrounded by happy little numbers, creating a beautiful border of mathematics.
Oh, dude, you're hitting me with the math questions now? Alright, alright. So, the perimeter of a rectangle is just adding up all the sides, like a little math reunion. In this case, with sides of 5m and 4m, you just add 'em up: 5 + 5 + 4 + 4 = 18 meters. Boom, there you go, perimeter party!
11x5 m is 32m
The perimeter of 4 meters by 5 meters is 18. Is the figure a square? if it is then the answer is 18m squared. The first answer is correct if the shape is a parallelogram; the second is rubbish. A square cannot be 4m by 5 m because one of the defining characteristics of a square is that its sides are the same length! The perimeter is the length (therefore metres, NOT m sq) around the shape. 4m+5m+4m+5m = 18m.

4m+9+5m-12=42 9m=45 m=5
The perimeter of a triangle is the sum of its three sides. If two are 3m and 2m then their sum is 3m + 2m = 5m And the remaining side can be calculated by taking this sum from the perimeter → the other side is 9m - 5m = 4m long.
Rectangles are really simple. The perimeter is twice the length plus twice the width (in this case 4m x 2 = 8m, 5m x 2 = 10m, and 8m + 10m = 18m). The area is simply the length times the width (in this case, 4m x 5m = 20m2).
The area of rectangle is : 20.0
Oh, dude, you're hitting me with some math lingo! So, if a rectangle has dimensions 5m by 3m, its perimeter would be 16m (2x5 + 2x3). To find another rectangle with the same perimeter, you could have dimensions like 4m by 4m (2x4 + 2x4 = 16m). It's all about balancing those sides, like a seesaw, man.
(4 + 1) × 2 = 10 metres
18m
Perimeter = 2*(40m + 5m) = 2*45m = 90m
Perimeter = 2*(40m + 5m) = 2*45m = 90m
16 metres.
Perimeter = 2*(4m + 85cm) = 2*4.85 m = 9.7 m
Well, darling, if the length of your rectangle is 4m and the width is 2m, then the perimeter is simply calculated by adding up all the sides, which gives you 4m + 4m + 2m + 2m, totaling 12 meters. VoilΓ , there's your answer!
11x5 m is 32m
(4 + 1) × 2 = 10 metres
