Question

A flower bed in a garden is in the shape of a triangle. The longest side is 3 times the middle side and smallest side is 2 units shorter than the middle side. Let P represent the length of the middle side, then what’s the perimeter in terms of P?

Answer 1

Solution.

Let, the middle side of triangle, AB be P.
then, the longest side of triangle, AC be 3P.
and shortest side of triangle, BC be (P-2).

Now, the perimeter of triangle ABC,
➡AB + BC + AC
➡P + P-2 + 3P
➡5P - 2.

Hence the perimeter of triangle is (5P-2) units.

Hope this will help you. ✌✌☺
