The area of the triangle is 48cm. then find the length of corresponding altitudes

Area of triangle = 1/2 × base × height 
Base of the triangle = (2 Area)/height 
Height of the triangle = (2 Area)/base 

Given:
A = 48 cm^2
Base of the triangle = (2 x 48 )/height
Height of the triangle = (2 x 48)/base
 Let the triangle be isosceles :
So,
base = height

Therefore,
Base of the triangle = (2 x 48 )/Base
(Base)^2 = 96
Base = √96
Base = √(2*2*2*2*6)
Base = 4√6
height = 4√6

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
