Question

The area of the triangle, shown below, is 39 c m 2. What is the height of the triangle?

Answer 1

Area =

`A\text{ = }(1)/(2)* b* h`

where A is the area

b is the base

h is the height

From the figure

A = 39

b =13

substitute the values into the formula and solve for h

`39=(1)/(2)*13* h`
`39=(13h)/(2)`

cross multiply

78 = 13h

Divide both-side of the equation by 13

h = 6

The height of the triangle is 6 cm
