<h2>Given </h2>
Triangle with:
- Base of n² -3,
- Midsegment of 39.
<h2>To find</h2>
<h2>Solution</h2>
As per definition of midsegment, it is connecting the midpoints of two sides and its length is half the length of the opposite side of the triangle.
So we have:
Solve it for n:
- n² - 3 = 78
- n² = 81
- n = √81
- n = 9
Correct choice is D.
Answer:
B
Step-by-step explanation:
you cut it where the little box is. so that is 9. then you do 5 times 8 to get 40. 40+9=49
Answer: 64 feet.
Explanation:
Perimeter formula: 2l + 2w
Area formula: l•w
Length = 3w
Area = 192 ft
192 = (3w) • w
192 = 3
192 ÷ 3 = 3
÷ 3
64 =
=
8 = w
Width = 8
Length = 3(8) = 24
Perimeter = 2(24) + 2(8) = 64 feet.
