Answer: 30.51900
Step-by-step explanation:
(30 g) + (519 mg) = 30.51900
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
A and C i believe that’s correct
5 x 1/4 = 1 1/4 or 1.25
4 x 1/2 = 2
1.25 + 2 = 3.25 or 3 and 1/4
A = b * h
b = 8 2/3
h = 5 3/4
A = 8 2/3 * 5 3/4.....turn to improper fractions
A = 26/3 * 23/4
A = 598/12
A = 49 5/6 ft^2 <====
