A trapezium has parallel sides of 4 cm and 14 cm and a height of 3 cm. What is its area?
Answer and explanation
Correct answer: B. 27 square cm
- Step 1: Area = half x (sum of parallel sides) x height.
- Step 2: = 1/2 x (4+14) x 3 = 27.
Answer
27 square cm.
Why not the others: 54 square cm: the factor one half was left out. 84 square cm: the parallel sides were multiplied instead of added. 21 square cm: the three lengths were added.
