Answer:

360 cm^2.

Step-by-step explanation:

Area of the base = 10*10 = 100 cm^2.

We find the slant height of the sides using Pythagoras:

h = sqrt ( 12^2 + 5^2)

h = sqrt 169

h = 13.

Area of the triangular sides = 4 * 1/2 * 10* 13

= 260 cm^2

So the total surface area = 100 + 260

= 360 cm^2.

Fine the value for X that makes

Nesterboy [21]

Answer:

Step-by-step explanation:

x and 2x are linear pair angles.

Sum of linear pair angles is 180,

x + 2x = 180

3x = 180

x = 180 / 3

x = 60

Therefore,

the value of x is 60.

A rectangle is 6yards longer than it is wide. Find the dimensions of the rectangle if it’s area is 187 square yards

emmasim [6.3K]

Answer:

Width = 11 yards

Length = 17 yards

Step-by-step explanation:

First of all, the length of the rectangle is 6 yards longer than the width, this means, length = width + 6 yards. This dimensions can be represented on figure 1, where <em>w</em> is width, and <em>l</em>, for length.

We know the area of a rectangle is A = width x length

For our case 187 = w . (w + 6)

Using the Distributive Property for the multiplication we obtain

$187 = w^{2} +6w$

$w^{2} +6w-187 =0,$

Using the quadratic formula $w=\frac{-b\±\sqrt{b^{2}-4ac } }{2a}$ where a = 1, b = 6, c = - 187 and replacing into the formula, we will have:

$w=\frac{-6\±\sqrt{6^2-4(1)(-187)} }{2(1)}$

$w=\frac{-6\±\sqrt{36+748} }{2}=\frac{-6\±\sqrt{784} }{2}=\frac{-6\±28}{2}$

We have two options: $w=\frac{-6+28}{2}=\frac{22}{2}=11 yards$

$w=\frac{-6-28}{2}=\frac{-34}{2}=-17 yards$ But a distance (width) can not be negative so, this answer for w must be discarded.

The answer must be width = 11 yards.

To find the length $l =\frac{187}{11}=17 yards$
