Trapizoid area formula = (b1+b2)/2×h
rectangle formula =l×w
trapizoid 1: (12+16)/2×5
trapizoid 2: (12+16)/2×5
rectangle: 10×12
solve
t1 + t2:
(12+16)/2×5
28/2×5
14×5=70 +70=
140 ft^2
r: 10×12=120ft^2
140-120=20ft^2 of wood

Answer:
25 feet
Step-by-step explanation:
Given that Sally is at the park standing directly under a kite which is 20 feet overheadSally's dad is flying the kitc and is standing 15 feet from her If both are on level ground, how long is the kite string in feet?
To calculate the length of the kite string, we will apply pythagorean theorem.
Length = sqrt ( 20^2 + 15^2 )
Length = sqrt ( 400 + 225 )
Length = sqrt ( 625 )
Length = 25 feet.
Therefore, the length of the kite string is 25 feet.
a^2 + b^2 = c^2 pythagorean theorem
7^2 +24^2 = 25^2
49 + 576 = 25^2
625 = 25^2
25^2 =25^2
a^2 + b^2 = c^2 pythagorean theorem
9^2 + 40^2 = 41^2
81+1600 = 41^2
1681 = 41^2
41^2 = 41^2
