What is the area of a triangle with a 4m base and a 5m height?
Show answer Hide answer
Answer: B. 10 sq m
Explanation
The formula for a triangle's area requires multiplying one half by the base and height. Multiplying four meters by five meters and dividing by two gives the correct numerical product. The calculated area equals exactly ten square meters based on standard geometric rules. The area of a triangle represents the two dimensional space enclosed by its three straight sides. Base and height measurements must be perpendicular to each other for standard area formulas to apply. Square meters are the standard international unit for measuring two dimensional surface areas.
Calculating triangular areas is essential when tiling floors or painting triangular architectural features. Surveyors divide irregular plots of land into triangles to compute total property acreage accurately. Basic geometry provides foundational skills required for advanced spatial reasoning and technical drafting. Option a represents twenty square meters which forgets to divide the product by two. Option c underestimates the correct area calculation by a factor of two. Option d provides an incorrect low value that does not match the multiplication results.
