Answer:
The perimeter of this triangle should be 34 units.
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
I assume that x = figure no.
It's better to write this as
Tiles = 10n-18
Thus 10(12) - 18
=120 - 18
= 102
THUS HE IS WRONG.
