The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the rectangle has a length of 7 meters and a width of 3 meters. To find the perimeter, you would add the lengths of all sides: 7m + 7m + 3m + 3m = 20 meters. Therefore, the perimeter of a rectangle with dimensions 7m x 3m is 20 meters.

32 meters The perimeter (distance around the outside) = length + width + length + width P = 2L + 2W 2 (9) + 2 (7) = 18 + 14 = 32 also: P = 2 (L + W) 2(9 + 7) = 32


How do you calculate the area of a triangle with a base equal to 3m and height equal to 6m?

This is not the question I was looking for.1Record the length and width of a square or rectangle. Substitute your measurements into the formula "length x width" to solve for area. For example, a rectangle with a length of 7 meters (m) and a width of 3m has an area of: 7m x 3m = 21m^2 (21 meters squared, or 21 square meters).2Use the formula "(base x height)/2" to find the area of a triangle. A triangle with a height of 7m and a base of 3m has an area of 7m x 3m = 21m^2, divided by two equals 10.5m^2.


What is the perimeter of rectangle 7m long and 4m wide?

well if you add it it is easy. A:11m.The above is a load of bovine droppings. P = 2(L + W) so the CORRECT answer is 22 m.The perimeter of a rectangle is 2 x (length + width).2 x (7m + 4m) = 2 x 11m = 22m

What is the perimeter of a rectangle 3m x 1.5m?

9 meters The perimeter (distance around the outside) = length + width + length + width P = 2L + 2W 2 (3) + 2 (1.5) = 6 + 3 = 9 also: P = 2 (L + W) 2(3 + 1.5) = 9


What is the perimeter of a rectangle with an area of 49 and a length of 7m?

28 meters It would be a square because A = L x W so 49 = 7 x W and the width is 7. Its perimeter is 4*7 = 28 meters.
