Answer:
The answer is below
Step-by-step explanation:
Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting rectangle AEFD?
A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel to each other.
A rectangle is a quadrilateral with opposite sides which are parallel and equal to each other. All the angles in a rectangle are at 90 degrees.
From the image, AD = z, FC = x, BF = w and BC = y. Hence:
EB = FC = x.
EF = AD = length = z; AE = FD = height = w
Therefore the dimensions of rectangle AEFD is length z and height w
Answer:
7.2 m²
Step-by-step explanation:
Use the appropriate area formula, fill in the given values, and do the arithmetic.
A = (1/2)ab·sin(C)
where "a" and "b" represent triangle side lengths and C is the angle between them.
A = (1/2)(4 m)(8.5 m)sin(25°) ≈ 7.2 m²
