Solution On #1:

Perimeter of Quadrilateral

A quadrilateral is a polygon with four sides and four vertices. It is from the word "quad" which means four and "lateral" which means side. It is a two-dimensional shape and has straight sides. The sum of its interior angles is 360°. Some examples of quadrilateral are square, rectangle, rhombus and trapezoid.

$\sf{Given}$

Perimeter - 412.95 cm

Three sides - 85.56 cm, 112.77 cm and 85.26 cm

$\sf{Equation}$

412.95 cm - (85.56 cm + 112.77 cm + 85.26 cm)

= 412.95 cm - 283.59 cm

= 129.36 cm

$\sf Final \ Answer$

129.36 cm.

Solution On #2:

Let x be the change.

ITEM 1 - ₱39.90

ITEM 2 - ₱68.60

ITEM 3 - ₱58.75

ITEM 4 - ₱120.25

Solution:

x = ₱500 - ₱39.90 + ₱68.60 + ₱58.75 + ₱120.25

x = ₱500 - ₱287.45

x = ₱212.55

Therefore, the change he will get from his ₱500 peso bill is ₱212.55.

$\sf Final \ Answer$

₱212.55.

Solution On #3:

Perimeter of the Rectangle

The perimeter of the rectangle refers to the total length of all the sides of the rectangle. Rectangle is a four-sided polygon where opposite sides are always the same in size. Therefore, to find the perimeter of the rectangle, you have to find the sum of twice its length and twice its width.
