Which Is the Best estimare of The área of The figure in square centimeters (as shown down) l need It in 5min

ycow [4]

Answer:

38.28cm²

Step-by-step explanation:

The area of the figure can be determined by expression the figure as two shapes.

A semicircle and trapezium;

Area of shape = Area of semicircle + Area of trapezium

Now;

Area of semicircle = $\frac{\pi r^{2} }{2}$

Where r is the radius, which is $\frac{4}{2}$ = 2cm;

Area of semicircle = $\frac{3.142 x 2^{2} }{2}$ = 6.28cm²

Area of trapezium;

= $\frac{1}{2} (a + b)h$

a and b are the base length = 6cm and 10cm

h is the height = 4cm

Input the parameters and solve;

= $\frac{1}{2} (6 + 10) 4$

= 32cm²

The area of the shape = 6.28cm² + 32cm² = 38.28cm²
