yes. add all sides together to find the perimeter. 7+8+10=25.
Perimeter = 3*25 = 75 cm
Perimeter: 15+20+25 = 60 units
Its perimeter is: 2*(10+2.5) = 25 m because its length is 25/2.5 = 10 m
If that's its length and width then its perimeter is: 2*(10+2.5) = 25 m
Yes
25
The perimeter of any triangle is the sum of its 3 sides
Perimeter = 3*25 = 75 cm
Perimeter: 15+20+25 = 60 units
The Formula for area of any triangle (including right) is: Base x height divided by 2 for example: the base of my triangle is 10 cm and the height of my triangle is 5 cm 10 x 5 divided by 2 = 25 cm squared
It depends on the shape. Let's say your lawn is 1 foot by 100 feet, which equals 100 square feet, then the surrounding measurement, called the 'perimeter', is 1+ 1+ 100+ 100 = 202 feet. Or, if the lawn is, say, 4 feet by 25 feet, which equals 100 square feet, the perimeter is 4+ 4+ 25+ 25 = 58 feet. If the lawn is perfectly square, its size would be 10 feet by 10 feet, and the perimeter is 10+ 10+ 10+ 10+ = 40 feet. The same is true for all dimensions in between: the perimeter changes as the shape of the lawn changes.
If it's a regular decagon then its perimeter is 10*25 = 250 cm
Its perimeter is: 2*(10+2.5) = 25 m because its length is 25/2.5 = 10 m
10
If that's its length and width then its perimeter is: 2*(10+2.5) = 25 m
How about: 11, 11, and 3 cm or as 7, 7 and 11 cm for its perimeter dimensions
Yes
