Question

A triangular flag has base one foot and height $1.5$foot. What is its area?

Short answer

The area of the triangle$A=0.75f{t}^2$

Step-by-step solution

Step 1. Given information

Triangluar flag has base 'b' $=1foot$

Height 'h'$=1.5foot$

Step 2. Finding the area of the triangle

Let Ais the area of the below show triangular flag ABC.

Formula of area of a triangle $A=\frac{1}{2}bh$

$$\begin{gathered} A=\frac{1}{2}\times 1\times 1.5 \\ A=0.75f{t}^2 \end{gathered}$$

Step 3. Checking

Check the solution by using the formula $A=\frac{1}{2}\times b\times h$

$$\begin{gathered} 0.75=\frac{1}{2}\times 1\times 1.5 \\ 0.75=0.75\left[true\right] \end{gathered}$$

Therefore,the area of the triangle$A=0.75f{t}^2$
