I don't think I understand what you mean, but I will guess. A quadrilateral must have 4 sides to it and have 4 vertices (corners).
Answer: 170
Step-by-step explanation:
The formula for the area of a triangle is 1/2bh, where b is the base length, and h is the height.
So- Essentially you’d just need to plug in the variables to solve this. the semicircle on the bottom serves to tell you the base length.
1/2(20)(17)
170
Answer:
a) x = 4 cm
Step-by-step explanation:
x + 2x + 2x = 20 cm
5x = 20
x = 4 cm
99 is 1 less than 100.
(100-1)×6
100×6=600
-1×6=-6
600-6=<span>594
Answer: 594</span>
