Answer:
18
Step-by-step explanation:
The x coordinate of vertex J and L are same of x= -2, JL // Y axis
Height is the perpendicular segment (KD) from K to JL, KD // X axis
area = JL * KD /2 = ((1 - -5)* (4 - -2)) / 2 = (6 * 6) / 2 = 18
Answer: 69
sides of triangle are (4+3) and (2+3)
or 7,5
area of triangle=1/2×7×5=35/2=17.5 cm²
area of rectangle=3×2=6 cm²
area of shaded region=17.5-6=11.5 cm²
I think it would be 14.2 and 8.8
