Louie and johnna made a table flag for the math team to have during competitions. the flag is shown below

To solve this we are going to use the formula for the area of triangle: 
where
is the area of the triangle 
is the base of the triangle 
is the height of our triangle

We can infer from the picture of our triangular flag that the base of the triangle is (3x)cm, so . We can also infer that the height of the triangle is (4x)cm, so . Lets replace the values in our formula:
" alt="A= \frac{1}{2} bh" />" />




We can conclude that the expression for the area of our flag is .

0.69 yards

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
