First of all, Jamie's room is really weird. Second of all, let's solve. Since the formula for the area of a circle is (pi)r^2, and Jamie's room is exactly half of that, the area for a semicircle would be (1/2)(pi)r^2. The straight wall is the diameter, so half of the diameter would be the radius. Half of 14 is 7. Now, you rewrite the equation and substitute the values of the variables. The new equation (if you're using 3.14 for pi) is (1/2)(3.14)(7^2), or (1/2)(3.14)(49). From here you can solve, so the answer would be 76.93. Jamie needs 76.93 square feet of carpet.
It also has a height equal to the pentagon's apothem. (Remember, the height of a triangle runs from a vertex to the opposite side, at a right angle.) To find the area of any triangle, just calculate ½ x base x height. In our example, area of triangle = ½ x 3 x 2 = 3 square units.
-3 + -4 = -7
add the numbers and keep the common sign.
-3 * -4 = 12
since the factors are both negative, the product is positive, when multiplying and/or dividing.
