Question

A triangle has a base of 3 2/5 inches and an area of 5 1/10 square inches. Find the height of the triangle. Show your reasoning

Answer 1

Answer:

Step-by-step explanation:

Area if a traiangle =1/2 × base × height

5 1/10 = 1/2 ×3 2/5 ×h

Change mixed fractions to improper fractions

51/10= 1/2 ×17/5 ×h

51/10 = 17/10×h

Divide 51/10 by the coefficient of h

51/10÷17/5 = h

51/10 ×5/17 = h

3/2 = h

h =1 1/2 inchea

The height of the triangle 1 1/2 inches
