scoray [572]

Answer:

3/20

Step-by-step explanation:

By question it's given that ,

$\implies \dfrac{a}{b}=\dfrac{2}{5}$

$\implies \dfrac{b}{c}=\dfrac{3}{8}$

And we need to find out the value of a/c .For that Multiply both of them , we have ;

$\implies \dfrac{a}{b} \times\dfrac{b}{c}=\dfrac{2}{5}\times \dfrac{3}{8} \\\\\implies \dfrac{a}{c}= \dfrac{3}{20}$

Hence the required answer is 3/20 .

Could someone help? Thank you

Answer:

See Below

Step-by-step explanation:

Thankfully, all the parts you need are given.

First, find the surface of one triangle

A = 1/2bh

A = 1/2(15)(9)

A = 1/2(135)

A = 67.5

Multiply by 4 to get the sum of all the sides.

67.5(4) = 270

Now find the surface area of one square

A = bh

A = (15)(15)

A = 225

multiply by 5 to get all 5 sides

225(5) = 1125

Add sums together

1125 + 270 = 1395
