Question

Given that is the midpoint of AB and E is the midpoint of AC, AD =32cm, AE=19cm, and DE=39cm, determine the perimeter of DBCE

Answer 1

since triangle AED similar to ACB

CE=19cm mid point bisect it

BD=32Cm mid point bisect it

Explanation:

BC=2DE=2×39=78Cm

• perimeter=sum of all side=ce+de+bd+bc=19+39+32+78=168cm
• therefore perimeter of DBCE=168Cm
