L=3W
Area=LW=6627
Plug in the first one in the second one.
3WW=6627
W^2=2209
W=47
L=3*47=141
Answer:
Missing side=25 units.
Area of the figure= 470 sq units.
Step-by-step explanation:
The figure is made up of a rectangle and a triangle.
To get the base of the triangle, we find the difference between the two parallel sides, that is, 16ft and 31 ft.
31ft-16ft=15ft
The height of the triangle is 20 since it is parallel and equal to the length of the rectangle.
We therefore use pythagoras theorem to find ?
a²+b²=c²
15²+20²=c²
625=c²
c=25
ii. The figure is a trapezium therefore we use the following formula to find the area.
A= 1/2(a+b)h, where a and b are the two parallel sides. and h the distance between them.
=(1/2)(31+16)×20
=470 sq units
99.99 - 64.25= 35.74
35.74/64.25= 0.556=55.6% or 56% rounded
Answer:
Step-by-step explanation:
By definition, a relation is a function if each input value has one and only one output value.
The input values are the x-values and the output values are the y-values.
Given:
and 
We can identify that we need to find the output values of these input values:
Observe in the graph attached that:
- When

- When
Therefore:
