Answer:
16 cm²
Step-by-step explanation:
The figure is a trapezoid with two parallel sides.
The formula for the area is
A = ½(a + b)h
Data:
a = 5 cm
b = 3 cm
h = 4 cm
Calculation:
A = ½(5 + 3) × 4 = ½ × 8 × 4 = 16 cm²
The area of the trapezoid is 16 cm².
Answer: 40
Step-by-step explanation:
Answer:B
V = l. w. h
Step-by-step explanation:
Volume of a rectangular prism is base area * height
The base is a rectangle, hence, the base area equals area of a rectangle which is length * width
Replacing base area (B) in the formula,
V = Bh
V= l * w * h
I just found 10% of it, which is 14, then found 5% of it through the previous work, which is 7
then i multiplied 7 by 11, because 55/5 is 11, so 55% of 140 is 77
