Answer:

Area: 16.5 square inches

Perimeter: 20.6 inches

Type: Right triangle

Step-by-step explanation:

The formula for the area of a triangle is 1/2bh, so substitute ‘a’ for ‘b’ and ‘b’ (from the question) for ‘h’.

1/2*7.5*4.4 = 16.5

Perimeter is the sum of all three sides, so add a+b+c.

7.5+4.4+8.7 = 20.6

The triangle has a right angle, so it is a right triangle.
