Rylie is tiling her patio with square tiles.  The patio is triangular with a base of 20 feet and a height of 16 feet.  Which equation can be used to find A, the area of the patio in square feet?ResponsesA A = 0.5(20 + 16)A = 0.5(20 + 16)B A = 0.5 + (20 • 16)A = 0.5 + (20 • 16)C A = 0.5(20 • 16)A = 0.5(20 • 16)D A = 0.5 + (20 + 16)

A triangle has a base of 24 inches and an area of 260 square inches.  Which equation can be used to find h, the height of the triangle?ResponsesA 24h = 26024 h = 260B 12h = 26012 h = 260C 48h = 26048 h = 260D 260h = 12

Sam decides to build a square garden. If the area of the garden is 9x2 − 24x + 16 square feet, what is the length of one side of the garden? (3x + 4) feet (3x − 4) feet (4x − 3) feet (4x + 3) feet

A trapezoid has base lengths of 10.5 units and 16 units.  The height of the trapezoid is one-half as long as the longer base.  What equation could be used to find the area of the trapezoid?ResponsesA A = 0.5 × (10.5 + 16)A = 0.5 × (10.5 + 16)B A = 0.5 × 0.5 × (10.5 + 16)A = 0.5 × 0.5 × (10.5 + 16)C A = 0.5 × 8 × (10.5 + 16) A = 0.5 × 8 × (10.5 + 16) D A = 0.5 × 8 × 16

Anna needs to find the area of a figure that can be separated into a square and a triangle. The base of the triangle is 18 cm, and its height is 10 cm. The length of the side of the square is equal to the base of the triangle. Which expression can Anna use to find the area of the figure?ResponsesA (18) + 12(18)(10)(18) + 1 2 (18)(10)B 2(18) + 12(18)(10)2(18) + 1 2 (18)(10)C (18)2 + (18)(10)( 18 ) 2 + (18)(10)D (18)2 + 12(18)(10)

In a land of triangular shape ∆ABC , a line DE intersects the sides AB and AC in such a way that AB : BD = AC : CE. If the area of the land shaped as ∆DBC is 10 sq. meters, what is the area of ∆BEC?
