Question

which figure has a greater area? 19 mm 20 mm 16 mm 11 mm

Explanation:

Step1: Calculate triangle area

Use formula $A_{triangle}=\frac{1}{2}\times base\times height$. Here base = 20 mm and height = 19 mm. So $A_{triangle}=\frac{1}{2}\times20\times19= 190$ $mm^{2}$.

Step2: Calculate parallelogram area

Use formula $A_{parallelogram}=base\times height$. Here base = 11 mm and height = 16 mm. So $A_{parallelogram}=11\times16 = 176$ $mm^{2}$.

Step3: Compare areas

Since $190>176$, the triangle has a greater area.

Answer:

The triangle has a greater area.
