Question

What is the missing length?Area of shaded region = 184 mm^2.p = ___ milimeters.

Answer 1

The formula to calculate the area of a triangle is

`A=(p\cdot b)/(2)`

in our case we have p is the height of the triangle, and b is the base of the triangle

A=184 mm^2

b=16mm

we substitute the data given

`184=(p\cdot16)/(2)`

then we isolate the p

`p=(184\cdot2)/(16)`
`p=23`
