The base of a triangle is 2 ft. The
height of the triangle is 15 in. What is the area
of the triangle in square inches?

The area of the triangle is 180 square inches

Step-by-step explanation: The question gives us a triangle with the dimensions as

Base = 2 feet

Height = 15 inches

However the answer should be expressed in inches, which means we have to convert the measurements in feet to inches. Remember that 12 inches make one foot. Therefore, two feet would simply be

12 x 2

= 24 inches

With the dimensions now given as

Base = 24 inches

Height = 15 inches

Area of the triangle = ½B x H

Area of the triangle = ½ x 24 x 15

Area of the triangle = 12 x 15

Area of the triangle = 180 square inches

x = 1.146 and x =7.854

Step-by-step explanation:

Use the quadratic formula

x = -b ± √b² -4ac
