Question

the perimeter of the triangle?
The foot of a ladder rests at a distance
of 36 m from a wall and the top of the
ladder rests on the wall at a height of 15​

Answer 1

Answer:

90m

Step-by-step explanation:

here it is a right angle triangle

so hypotenuse is to be found n then perimeter

perpendicular length= 15 m

base= 36m

so hypotenuse is

H2= p2+B2

H2= 15^2+36^2

H2= 225+1296

h=√1521=39m

so perimeter is( 15+36+39)m= 90m

Answer 2

Answer:

base=36m

h=15m

(perpendicular)²= b²+h²

=> p²=1296+225

=> p²=1521

=> p= 39

Therefore, the perimeter of triangle =p+b+h=39+36+15=90

(p=perpendicular

b=base

h=height)
