Answer:
The base ( AB ) of triangle ABC is 800m
Step-by-step Explanation :
( Please see the attached document for diagram )
Given : Area of triangle = 48m²
Height CD = 12cm = 0.12m ---------- ( since 1m = 100cm )
To find : Base ( AB ) = ?
We know that,
Area of Triangle = 1/2 × base × height
So,
Area of ∆ ABC = 1/2 × AB × CD
Substituting the given value in above formula we get,
48 = 1/2 × AB × 0.12
48 × 2 = 0.12 × AB
96 = 0.12 × AB
AB = 96/0.12
= 800 m
Hence the base ( AB ) of triangle ABC is 800m
