Altitude = sqrt [(4sqrt5)^2 - 862 = 4 ft
Perimeter of the trapezoid = 8+4+16+4sqrt5 = 28+4sqrt5
= 36.94 feet to nearest hundredth answer
Area = 1/2 * 4 * (8+16) = 48 ft^2 answer
Answer:
the answer is 60 x 10^3 in scientific notation
Step-by-step explanation:
Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
