Nancy has a big chocolate bar shaped like a rectangular prism. It is 15 centimeters long, 14 centimeters wide, and 2 centimeters

Leya [2.2K]

Answer: $420 cm^{3}$

Step-by-step explanation:

The volume $V$ of a rectangular prism is given by:

$V=(length)(width)(thickness)$

If the chocolate bar has the following dimensions:

$length=15 cm$

$width=14 cm$

$thickness=2 cm$

Its volume is:

$V=(15 cm)(14 cm)(2 cm)$

$V=420 cm^{3}$

If m = 7x + 7, m = 4y, and m = 112, find the values of x and y

tester [92]

If m = 7x + 7, m = 4y, and m = 112

since m = 112

112 = 7x + 7
112 - 7 = 7x
105= 7x
x = 15

112 = 4y
y = 28

Find the area of the following polygon:

Masja [62]

Given:

ABCD is a quadrilateral

AC = 12, DE = 4 and FB = 5

To find:

The area of the polygon.

Solution:

AC bisects the quadrilateral into two triangles.

Area of triangle:

$$A=\frac{1}{2}\times\text{base}\times\text{height}$

Area of triangle DAC:

$$A=\frac{1}{2}\times AC \times DE$

$$A=\frac{1}{2}\times 12 \times 4$

$A=24$

Area of triangle DAC = 24 square units.

Area of triangle BAC:

$$A=\frac{1}{2}\times AC \times FB$

$$A=\frac{1}{2}\times 12 \times 5$

$A=30$

Area of triangle BAC = 30 square units.

Area of polygon = Area of triangle DAC + Area of triangle BAC

= 24 square units + 30 square units

= 54 square units

The area of the polygon is 54 square units.
