Find the area of the following parallelogram.
Step 1:
Area of Parallelogram = b × h; b = base = 14 in; h = height = 6 in.
Step 2:
Area of given parallelogram = 14 × 6 = 84 square in.
Find the area of the following parallelogram.
Step 1:
Area of Parallelogram = b × h; b = base = 40 in; h = height = 15 in.
Step 2:
Area of given parallelogram = 40 × 15 = 600 square in.
Find the area of the following trapezoid.
Area of Trapezoid = (1/2) x h x (b1+b2 )
b1, b2 = bases = 3, 4; h = height = 5.
Step 2:
Area of trapezoid = (1/2) × 5 ×( 3+4) = 17.5 square in.
