What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

From the given figure,

Height of a triangle is 8 units and the base of the triangle is 6 units.

Here, area = 1/2 ×6×8

= 24 square units

Therefore, option B is the correct answer.

A cube is removed from a rectangular prism. Find the surface area of the figure after removing the cube.

Answers

Answer:

Step-by-step explanation:

Rectangular prism:

l =9 ft ;  w = 8  ft ; h = 5ft

Area1 = Surface area of rectangular prism without top  = lw + 2wh + 2lh

                                          = 9*8 + 2*8*5 + 2*9*5

                                         =  72 + 80 + 90

                                         = 242 sq.ft

Cube:

a = 5 ft

Area2 = Surface area of cube without top = 5a²

                                         = 5 *5²

                                         = 125 sq. ft

Area3 Surface area of the top = l*w - a²

                                       = 9*8 - 5²

                                       = 72 - 25

                                       = 47 sq.ft

Surface area of the figure after removing cube = area1 +area2 + area3

= 242 + 125 + 47

= 414 sq.ft

Answer:

364 square feet.

Write the expression using an exponent:

Answers

Answer:

1 x [tex]4.5^{5}[/tex]

Step-by-step explanation:

The given expression can be written in exponent form as [tex]\mathbf{1 \times (\dfrac{4}{5})^5}[/tex]

What is the exponent of a number?

The exponent of a number is the power to which a number can be raised depending on its time of repetition. The way we do this generally is that we will first count the number of times a figure is repeated and raised that figure to the power of its repetition.

So from the given expression:

= 1.(4/5).(4/5).(4/5).(4/5).(4/5)

The number of times in which (4/5) is repeated is 5 times, so we have:

[tex]\mathbf{= 1 \times (\dfrac{4}{5})^5}[/tex]
