The vertical left edge of a trapezoid is 8 inches and meets the bottom edge of the trapezoid at a right angle. The bottom edge is 4 inches and meets the vertical right edge at a right angle. The right edge is 11 inches. The top slanted edge measures 5 in
Calculate the area of the trapezoid, which is not drawn to scale.
My answer : (5+4) divided by 1/2 x 11 (h) = 49.5
Nope,
area = (1/2)(sum of the two parallel sides)(distance between them)
= (1/2)(8+11)(4) =
notice the top slanted edge being 5 in does not enter the picture and was not needed
So 38 would be my answer?
yes
Ok thank you so much :)
Omg the
To calculate the area of a trapezoid, you need to use the formula:
Area = (1/2) * (a + b) * h
Where:
- a is the length of the bottom edge of the trapezoid.
- b is the length of the top edge of the trapezoid.
- h is the height of the trapezoid.
Given information:
- Bottom edge: 4 inches
- Top edge: 5 inches
- Vertical left edge: 8 inches
- Vertical right edge: 11 inches
As mentioned, the vertical left edge meets the bottom edge at a right angle. So, the height of the trapezoid is 8 inches.
Now, let's plug the values into the formula:
Area = (1/2) * (4 + 5) * 8
= (1/2) * 9 * 8
= (9/2) * 8
= 36
Therefore, the area of the trapezoid is 36 square inches.
