What is the area of the trapezoid?

ratelena [41]

Answer:

29.5 inches squared

Step-by-step explanation:

The formula for the area of a trapezoid is $\frac{base1 + base2 * height}{2}$ ,

so base1 = 14 inches and base2 = 30 inches

since there is a right angle, you know that the height must equal the length of the left side, so the height = 15 inches

then, 14+30+15=59 and 59/2=29.5

therefore, your answer would be 29.5 inches squared

A park has a large circle painted in the middle of the playground area.thecircle is divided into 4 equal sections And each secti

lilavasa [31]

Answer:

The area of each section of the circle is $25\pi\ m^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=10\ m$

substitute

$A=\pi (10^{2})=100\pi\ m^{2}$

To find the area of each section divide the complete area of the circle by $4$

$100\pi\ m^{2}/4=25\pi\ m^{2}$
