Question

Find the perimeter of the given figure. If ABC is a right angle triangle at B and AB=15m, BC=20m and BP=8m and also area of triangle is 100m².​

Answer 1

Answer:

perimeter of a triangle = sum of all sides

(15 +20+8)= 43 is the first answer

Step-by-step explanation:

please mark me as branliest

Answer 2

Answer:

60m

Step-by-step explanation:

Using Pythagoras theorem

(AC)² = (AB)²+(BC)²

(AC)² = (15)²+(20)²

(AC)² = 225+400

(AC)² = 625

AC = √625

AC = 25

Then,

Perimeter of triangle = a+b+c (sum of all sides)

→ 15+20+25

→ 60m
