Question
The table given below contains some measures of the right angled triangle. Find the unknown values.
| Base | Height | Area |
| 5 feet | ? | 20 sq.feet |
Solution
Area of the right triangle = `1/2 xx ("base" xx "height") "unit"^2`
b = 5 feet
Area = `1/2 xx "b" xx "h" "unit"^2`
20 = `1/2 xx 5 xx "h" "sq.feet"`
`(20 xx 2)/5` = h
h = 8 feet
Tabulating the unknown values
| Base | Height | Area |
| 5 feet | 8 feet | 20 sq.feet |
