Question

What is the area of CDE?Area = ____ square units.

Answer 1

The formula to calculate the area of a triangle is

`A=(b* h)/(2)`

the b is the base and h is the height

in this case

b= distance between D and E=13

h= distance between D and C=3

we substitute the values in the formula

`A=(13\cdot3)/(2)=19.5u^2`

the area is 19.5 square units
