The sum of interior angles in a rectangle is 360°

98 + 98 + 98 + 2x = 360

294 + 2x = 360

A square pyramid has a base area of 36ft2 the pyramids total surface area is 144ft2 what is the area of each triangular face?

JulijaS [17]

So a square pyramid is like the pyramids in egypt so
surface area of pyhraid=base+4 triangles
surface area=144
baswe=36
subsitute
144=36+4 times triangles
subtract 36 from both sides
108=4 triggles
divide by 4
27=trignels

the area of 1 triangle is 27 ft^2

The 3 by 3 grid below shows nine 1 cm × 1 cm squares and uses 24 cm of wire. What length of wire is required for a similar 20 by

Nady [450]

Answer:

840

Step-by-step explanation:

Hi there!

Usually, this kind of problem asks us the perimeter rather than the area. But when talking on this grid on how many cms are necessary to construct one made up of 9 squares 1cm x1 cm. We need to check one thing: Some line segments will be used twice. So this is not a classical perimeter question.

1) So we either manually and carefully count it avoiding not doing it twice the same common line segments.

Or.

2) By just applying an algorithm, Where n is the <em>nxn</em> grid

$n(n+1)+n(n+1)=Length \:of \:the \:wire$
