The base of a triangle is four times its height and its area is 50 $m^{2}$. The length of the base is
10 m
15 m
20 m
25 m
Explanation:
From given question we know that
b=4h----->(1)
Area of triangle=1/2 b*h=50m^2
b*h=50*2
b*h=100----->(2)
substitute b=4h in equation(2)
then,4h*h=100
h*h=100/4
h*h=25
h=5 substitute in (1)
b=4h
b=4*5
therefore base b=20m
