Three triangles are shown on the centimetre grid. A, B,C. A\ Which triangle has the largest area? b\ work out of the area of the triangle. Give your answer as a decimal.

Step-by-step explanation:

The three triangles are shown in the image attached.

Remember that the area of a triangle is determined by

Where is the base and is the height.

The first triangle is a right triangle with height of 4 units, and a base of 5 units. So, its area is

Therefore, the first triangle (at the left), has an area of 10 square units.

The second triangle (middle), has a height of 5 units and a base of 4 units, so its area is

Therefore, the second triangle has an area of 10 square units.

The third triangle has a height of 5 units, and a base of 4 units. Therefore, it also has an area of 10 square units.

Therefore, all three triangles are congruent.

the answer is 11.2 (i know i’m late)
