The triangle has a perimeter of 65 feet. What are the lengths of sides l, m,
and n
?

l = 10 feet, m = 30 feet and n = 25 feet

Step-by-step explanation:

The attached figure shows a triangle in which three sides as as follows :

, m and

Perimeter of triangle is 65 feet.

Perimeter = sum of all sides

put the value of n

Now put the value of l

⇒

And

Hence, l = 10 feet, m = 30 feet and n = 25 feet.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
