Well. The formula for the area of a trapezoid is b1 + b2 over 2 times h.
a = b1 + b2 (h)

Step-by-step explanation:
<u>Given:</u>
A circle with a diameter of 20 m inside a triangle with a base length of 56 m and a height of 56 m.
<u>To find:</u>
The area of the shaded region.
<u>Solution:</u>
To find the area of the shaded region, we must subtract the area of the circle from the area of the triangle.
The area of a circle
The diameter of the circle is 20 m so the radius is m.
The area of the circle square m.
The area of a triangle
The triangle has a base length of 56 m and a height of 56 m.
The area of the triangle square m.
The area of the shaded region square m.
The area of the shaded region is 1,254 square m.
136 sq km ÷8km is 17, because 8 in 136 can go into 13 once and 13 -8 =5 , thdn you bring down the 6 and 56 ÷8=7 so its 17
