A pennant is in the shape of an isosceles triangle. The base of the triangle is 9.5 inches, the height is 15 inches, and the length of the leg is 15.6 inches. What is the area of the pennant?
A flowerbed in a city park is in the shape of a trapezoid. The two parallel sides have lengths of 11 yards and 13 yards. The distance between the parallel sides is 9 1 over 2 1 2 yards. What is the area of the flowerbed?
Draw the figure.
A = 1 over 2 1 2 bh
A = 1 over 2 1 2 (9.5 in.)(15 in.)
A = 71.25 in.2
Draw the figure.
A = 1 over 2 1 2 (b1 + b2)h
A = 1 over 2 1 2 (11 yd + 13 yd)(9 1 over 2 1 2 yd)
A = 114 yd2
