gavmur [86]

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

<u>To find the Height and Base of given triangle</u>

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
