Answer:

70 cm^2

Step-by-step explanation:

The area of square is 5×10=50 plus the square of triangle, high of triangle is 18-10=8 and base of triangle is 5 because it common base with square, so the square of triangle is 1/2(8)(5)=20

The total area is 50+20=70 cm^2

Answer:  The correct option is (C) 70 cm².

Step-by-step explanation:  We are given to find the area of the figure shown in the picture.

We note that the figure is composed of rectangle and a triangle.

The length and width of the rectangle are

l = 10 cm  and  w = 5 cm.

So, the area of the rectangle is

A_r=l\times w=10\times5=50~\textup{cm}^2.

The base (b) of the triangle is 5 cm and the height (h) is  

h = 18 - 10 = 8 cm.

So, the area of the triangle is

A_t=\dfrac{1}{2}bh=\dfrac{1}{2}\times5\times8=20~\textup{cm}^2.

Therefore, the area of the figure is given by

A=A_r+A_t=50+20=70~\textup{cm}^2.

Thus, the required area of the given figure is 70 cm².

Option (C) is CORRECT.

Mrs. Bhatia's closet consists of two sections, each shaped like a rectangular prism. She plans to buy mothballs to keep the moth
AveGali [126]

Answer:

6.5 boxes

Step-by-step explanation:

Given

See attachment for closet

Required

Determine the number of boxes needed to fill the closet

First, we calculate the volume of the two section.

According to the attachment

The first section has the following dimension:

Width = 5ft

Length = 4ft

Height = 8ft

The second has the following dimension:

Width = 3ft ---- see the last label at the top

Length = 2ft --- This is calculated by subtracting the length of the first section (4ft) from the total length of the closet (6ft) i.e. 6ft - 4ft

Height = 8ft

So: The volume of the closet is:

Volume = W_1 * L_1 * H_1 + W_2 * L_2 * H_2

Volume = 5ft * 4ft * 8ft + 3ft * 2ft * 8ft

Volume = 160ft^3 + 48ft^3

Volume = 208ft^3

The number of box needed is then calculated by dividing the volume of the closet (208ft^3) by the volume of each box (32ft^3)

Boxes = \frac{208ft^3}{32ft^3}

Boxes= \frac{208}{32}

Boxes = 6.5
