Question

Find the area and perimeter.

Hint: The height of a non-right triangle is the length of the segment of a line that is perpendicular to the base and that contains the opposite vertex.

A. 6x + 36; 10x + 3
B. 12x + 72; 10x + 3
C. 12x + 72; 3x + 10
D. 6x + 36; 3x + 10

Answer 1

Explanation:

Perimeter = 12 + x + 6 + 2x + 5

Perimeter = 3x + 23.

Area = ½ × b × h

Area = ½ × 12 × (x + 6)

Area = 6(x + 6)

Area = 6x + 36
