We have to calculate the area of the polygon. This polygon is made of a parallelogram and the right triangle. The area of the triangle: A 1 = a * b / 2 = 8 * 17 / 2 = 136 / 2 = 68 cm^2. The area of a parallelogram : A 2 = a * h = 17 * 6 = 102 cm^2. Finally: A ( polygon ) = A 1 + A 2 = 68 + 102 = 170. Answer: B. 170 cm^2.<span> </span>
Answer: Its A
Step-by-step explanation: Just count the lines and since there is 8 lines it would be ?/8 so we going to count up until the dot which stops at 3 soo it would be 3/8
Answer:
C 14
Step-by-step explanation:
7 ×4 ×1/2=14
because triangle area formula is A=1/2×B×H
B= base
H= height
Answer:
No
Step-by-step explanation:
(12 + 31) × 5 = 215
12 + 31 × 5 = 167
