The table given below contains some measures of the right angled triangle. Find the unknown values.

Base Height Area
5 feet ? 20 sq.feet
Advertisements

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
