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.

Answer:

For $\frac{6}{25} = \frac{d}{30}$ , d = 7.2

Step-by-step explanation:

Here, the given expression is $\frac{6}{25} = \frac{d}{30}$

To find the value of the variable d :

$\frac{6}{25} = \frac{d}{30} \implies d = \frac{6}{25} \times 30$

or, $d = \frac{180}{25} = \frac{36}{5 } = 7.2$

Hence, for $\frac{6}{25} = \frac{d}{30}$ , d = 7.2
