To find the amount of space the floor would cover, you will find the area of the rug. Because the rug has a diameter, it is a circle. Use the formula for finding the area of a circle.
A = pi x r^2 3.14 x 7^2 A = 153.86 square feet
David's rug will cover approximately 153.86 square feet.
To find the area of a triangle uses the equation base*height/2. For this equation, we have 26 * h/2 = 195. This means that 26 * h = 195 * 2. 26 * 15 = 390, so your answer is 15 cm.
