Answer:
320 ft²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h (a + b)
where h is the perpendicular height and a, b are the parallel bases
Here h = 16, a = 18 and b = 12 , thus
A = × 16 × (18 + 12) = 8 × 40 = 320 ft²
Answer:
B (dint take my work for it)
12x^2-4x=0
144x^2-4x=0
140x^2=0
/140 /140
x=0
Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₁=4 u
leg₂=7 u
Therefore:
hypotenuse²=(4 u)²+(7 u)²
hypotenuse²=16 u²+49 u²
hypotenuse²=65 u²
hypotenuse=√(65 u²)≈8.06 u
Answer: the length of the hypotenuse is 8.06 u
