Aarón made a picture frame with the dimensions show in the figure what is the area of the picture
tatuchka [14]

Answer:

Area of the picture is 72\textrm{ }cm^{2}

Step-by-step explanation:

Given:

Outer rectangle dimensions are 10 cm by 12 cm.

Inner rectangle dimensions are 6 cm by 8 cm.

Area of the picture given as:

Area=\textrm{Outer rectangle area}-\textrm{Inner rectangle area}

Outer rectangle area = 10\times 12=120\textrm{ }cm^{2}

Inner rectangle area = 6\times 8=48\textrm{ }cm^{2}

Therefore, the area of the picture is given:

Area=120-48=72\textrm{ }cm^{2}

What is the total surface area of this rectangular pyramid?
umka2103 [35]

Answer:

225 square feet

Step-by-step explanation:

the base of the pyramid would be 76 ft², since 12*6=72. Then you get the surface area of the sides. 2 of the sides would be 48 ft², since (12*8)/2=48. The other 2 sides would be 28.5 ft², since (6*9.5)/2-28.5. Then you just add the surface areas of all the sides; 76+48+48+28.5+28.5 to get 225.

Hope this helps! :)

What is the student’s error?
amm1812

Answer:

The answer to the question is 10a√2a(b + 2)

Step-by-step explanation:

To know the student's error, let us calculate the perimeter from the the start.

Dimension of the rectangle is given below:

√(50a³b²) and √(200a³)

Perimeter of a rectangle = 2(L + B) = 2L + 2B

2√(50a³b²) + 2√(200a³)

2 x 5ab√2a + 2 x 10a√2a

10ab√2a + 20a√2a

Factorise

10a√2a (b + 2)

Therefore, the student made an error by adding 10ab√2a and 20a√2a together.

Note: we can not add 10ab√2a and 20a√2a together since b is missing in one of the expression.

Therefore, the answer to the question is 10a√2a(b + 2).
