Answer:
Base = 5 cm
Height = 20 cm
Step-by-step explanation:
Points to remember
Area of triangle = bh/2
Where b - base of triangle
h - Height of triangle
To find the Height and Base of given triangle
It is given that,area of a triangle piece of stained glass is 50 centimeters
the height of the triangle is four times the base
h = 4b
Area = bh/2
50 = (b * 4b)/2
100 = 4b²
b² = 100/4 = 25
b =√25 = ±5
b = 5 then h = 4b = 4 * 5 = 20
Base = 5 cm and Height = 20 cm
ANSWER
base=5 cm, height = 20cm
EXPLANATION
The area of a triangle is
[tex]A = \frac{1}{2} bh[/tex]
From the question, A=50 and h=4b
We substitute into the formula to get;
[tex] \frac{1}{2} b \times 4b =5 0[/tex]
This implies that,
[tex]2 {b}^{2} = 50[/tex]
[tex] {b}^{2} = 25[/tex]
Take positive square root to get;
[tex]b = \sqrt{25} [/tex]
[tex]b = 5[/tex]
The base is 5 cm and the height is 20 cm.
