Answer:

4[1/2(5 x 6)] + 6x6

Step-by-step explanation:

The first part of the expression is <em>4[1/2(5 x 6)].</em> This is the formula to find the surface area of the triangles. A regular triangle's area is <em>1/2(l*w).</em> Since there are four trinagles, you have to multiply the whole expression by 4.

The second part of the equation is finding the surface area of the base which is a square. Since squares have four equal sides, its safe to say that you can use <em>6 * 6.</em>

Find the area. Round to the nearest tenth.<br>6 in.<br>5 in.<br>9 in.<br>in.<br>​
ycow [4]

Answer:

131 1/4 in.²

Step-by-step explanation:

To find the area of the figure, you would have to divide the figure into two parts.  The figure can be divided into two rectangles.

<u>Rectangle 1</u>

The length is 11 3/4 in.  The width is 6 in.

A = lw

A = (11 3/4 in.)(6 in.)

A = 70 1/2 in.²

<u>Rectangle 2</u>

The length is 9 in.  The width is 6 3/4 in.

A = lw

A = (9 in.)(6 3/4 in.)

A = 60 3/4 in.²

Add the two areas together.

70 1/2 in.²  +  60 3/4 in.²  =  131 1/4 in.²

Need help its sector area
Paladinen [302]

Area of sector

=  \frac{30}{360}  \times  \pi \times  {(radius)}^{2}

=  \frac{30}{360}  \times  \ \frac{22}{7}  \times  {(12)}^{2}

=  \frac{30}{360}  \times  \ \frac{22}{7}  \times  12 \times 12

so the area = 37.71 square metre
