the complete question in the attached figure

we know that

[area of the triangle]=b*h/2
where
b-------> is the measure of the base of triangle
h------> is the measure of the height  of triangle
so

[area of the pink triangle]=14*14/2-------> 98 in²
[area of the blue triangle]=14*27.5/2-------> 192.5 in²
so
[square inches of crepe paper needed to make one flag]=98+192.5
[square inches of crepe paper needed to make one flag]=290.5 in²

the answer is
290.5 in²
