Sheets of canvas have been hung over the waiting lines to provide shade. Each canvas sheet is in the shape of a triangle with side lengths of 50 feet, 75 feet, and 75 feet. What is the area of each canvas sheet

Answer 1

what is the altitude to the center of the 50 foot side?
h^2 + 25^2 = 75^2
from that find h
then
A = (1/2)(50) h = 25 h
