A triangular lot was formed by three straight lines. Bearing of line AB is N45E and is 160 m long; line AC and BC is 190 m long. Point E is 100 m from A on side AB connects point D on side AC which divides the area, making area AED to be 2/5 of the whole area. Find the distance DE. a. 120.6 m                 c. 99.01 m b. 109.1 m                 d. 88.14 m

Area Computations

The area is the mathematical estimation of the inner space occupied by any shape or object and area computation is the evaluation of how much inner space that particular shape or object has utilized. Simple applications include calculating the area of wall for the quantity of paint or plaster to be applied on it, area calculations for construction of a trapezoidal dam and how much material is required, calculating the area of a circle to determine the range or distance of wheels that they are capable of covering due to varied radii and so on.
