A. 6 ft²
B. draw a diagonal; each triangle would be half the area: 3 ft²
Step-by-step explanation:
Part A:
The area is the product of the length of one of the parallel sides and its distance from the other:
A = bh = (8 ft)(3/4 ft) = 6 ft²
__
Part B:
A parallelogram can be divided into two congruent triangles by either of its diagonals. Since the triangles are congruent, each will have 1/2 the area of the parallelogram. In this case, each triangle's area would be ...
(1/2)6 ft² = 3 ft²
Answer:
<h2>-13 - (-23) = -13 + 23</h2>
