A triangular field with base 40 m and height 30 m shares a side with a rectangle of length 40 m and breadth 25 m. Find the combined area and percentage of the triangle’s area in the total.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1,600 m2 and 37.5%.
Triangle area = × 40 × 30 = 600 m2
Rectangle area = 40 × 25 = 1000 m2
Combined area = 600 + 1000 = 1600 m2
Percentage of the triangle’s area in total = × 100 = × 100 = 37.5%
