Answer:

The surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.

Step-by-step explanation:

Slant height of square pyramid = l = 13 mm

Base length of square pyramid = b = 11 mm

Formula of surface area of square pyramid =b^2+2bl

Substitute the values in the formula :

Surface area of square pyramid =11^2+2(11)(13)

Surface area of square pyramid =407 sq.mm.

Hence the surface area of the square pyramid if the slant height is 13mm and the base length is 11mm is 407 sq.mm.

I need help with #11 - #14.
Aleonysh [2.5K]

Answer:

I can get you jump started a bit.

Step-by-step explanation:

So Each of those pairs of figures are Similar.

This means they have equal angle measures but different side lengths.

To find it, we have to make a <u>Proportion:</u>

<u>Example: #11</u>

<u />\frac{x+1}{3x+1} =\frac{8}{20}<u />

So let's solve the first one!

24x+8=20x+20\\4x=12\\x=3

Easy As Pie!

If you need more help, contact me! :)

Hope this Helps!
