Answer:
Area = 1/2 b x h
18 = 1/2 ((x) x 4x)
18 =1/2 4x^2
36 = 4x^2
36/4 = x^2
9 = x ^2
x = 3
Base = 3 m
Height = 4 x base = 4 x 3 = 12 m
Step-by-step explanation:
The area of the shaded part is: 42.14 ft² .
<h3>Area of Square</h3>
Area = s²
<h3>Area of Quarter Circle </h3>
Area = 1/4πr²
Thus:
Area of the shaded part of the figure = area of square - area of quarter circle
Area of shaded part = s² - 1/4πr²
s = 14 ft
r = 14 ft
Substitute
Area of shaded part = 14² - 1/4(3.14)(14²)
= 42.14 ft²
Therefore, the area of the shaded part is: 42.14 ft² .
