Use the Pythagorean theorem:

The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
64,500 would be the answer
Answer:
3000 square inches.
Step-by-step explanation:
First, scale this one up. Multiply each by 2. consider area of a trapezoid. A = 1/2 (b1 + b2) h. This will be 1/2 (20 + 30) * 20, so you'll get 500 square in. Then, multiply by 6 since Buffy is making 6 of them. 500 * 6 = 3000 square inches.
Area = 10.08 yd²
Solution:
The given shape is a trapezoid.
Length of top base (
) = 5.4 yd
Length of bottom base (
) = 1.8 yd
Height of trapezoid (h) = 2.8 yd
<u>To find the area of the trapezoid:</u>
Area of the trapezoid = 


= 10.08 yd²
Area = 10.08 yd²
