Answer:
rhombus = a quadrilateral with four congruent sides
rectangle = a quadrilateral with four right angles
parallelogram = a quadrilateral with two pairs of parallel sides
trapezoid = a quadrilateral with one set of parallel sides
square = a quadrilateral with four right angles and four congruent sides
The area of polygons formulas to V=2.56m^2
We have to determine,
The volume of the pyramid.
<h3>What is the volume of the pyramid?</h3>
The volume of a pyramid is found using the formula,
V = (1/3) Bh
where 'B' is the base area and 'h' is the height of the pyramid.
hight =2.4m
base=1.4+1.8
base=3.2m
V = (1/3) (3.2)(2.4)
V=2.56m^2
As we know the base of a pyramid is any polygon,
we can apply the area of polygons formulas to find 'B.
V=2.56m^2.

Answer:
The missing side length is 6.
Step-by-step explanation:
Because the two triangles are similar,
the following equation of ratios is true:
m 4
----- = -----
15 10
Cross-multiplying, we get:
10m = 60, or m = 60/10 = 6
The missing side length is 6.
Let
x--------> original length side of a square
we know that
area rectangle=length*width
area=126 in²
length=(x+8)
width=(x-3)
so
126=(x+8)*(x-3)------> x²-3x+8x-24=126----> x²+5x-150=0
using a graph tool------> to resolve the second order equation
see the attached figure
the solution is
x=10 in
the answer isthe original length side of a square is 10 in
