Answer:
784 in² of wood
Step-by-step explanation:
Sarah needs two supports by shelf, and she will build 4 shelves
then she will need 8 supports
Now each support is a right isosceles triangle.
Area of a triangle is
A(t) = 1/2 *b*h where b is the base and h is the heigh of the triangle.
A right isosceles triangle has two sides ( base and heigh equals) and in our particular case are equals to 14 in, therefore
A(t) = 1/2*14*14
A(t) = 98 in²
Sarah needs 8 pieces of 98 in² she needs
A = 8*98
A = 784 in² of wood
