Yes they can be the same size
Answer:
The length of river D is 2550
length of river C is 2550+500=3050
Step-by-step explanation:
Let the river D be 'x'
and the river C is (x+500)
x + x + 500 = 5600
2x + 500 = 5600
2x = 5600 - 500
2x = 5100
x = 5100/2
x = 2550
The length of river D is 2550
length of river C is 2550+500=3050
Answer:
12
Step-by-step explanation:
Answer: 72 cm²
Step-by-step explanation: 1/2(base)(height) is the formula to find the area of a triangle. To find the area of the bigger triangle we substitute 10 cm for the base and 6 cm for the height.
1/2(10)(6)
1/2(60)
30 cm²
since we have two of the same triangles, we double that
we also have a smaller triangle. 14-10=4 which is the base of the smaller triangle.
1/2(4)(6)
1/2(24)
12 cm²
now, we add everything
60 cm² + 12 cm² = 72 cm²
