Question

A triangle has base 2 3/8 feet and height 2 1/4 feet. Find the area of the triangle as a mixed number.

Answer 1

Area of a triangle is given by the formula;

$A=\frac{1}{2}\times b\times h$

where A is the area of triangle

b is the base and h is the height.

From the question given:

b= 2 3/8 = 19/8

h= 2 1/4 =9/4

Substitute the values into the formula and evaluate.

$A=\frac{1}{2}\times\frac{19}{8}\times\frac{9}{4}$$=\frac{171}{64}$$=2\frac{43}{64}\text{ square f}eet\text{ }$
