The Perimeter is x+38
OLga [1]
P=x+38

add all individual sides together (is also the perimeter):
p=(x+3)+(x-5)+x+(x-2)+(x-4)+(x-1)+(x-1)
=7x-10

set both p equal:
x+38=7x-10
38=6x-10
48=6x
8=x

then insert x=8 in all the side/perimeter equations:
p=x+38=8+38=46

sides:
x=8
x-2=8-2=6
x-1=8-1=7
x-4=8-4=4
x-5=8-5=3
x+3=8+3=11

Whats the suface area?
Fiesta28 [93]

We can see that

There are four triangle on the surface

and five squares

For finding surface areas , we will find area of each surface and then add them

Calculation of area of triangle:

We are given

base=b=8

height=h=10

now, we can use area formula

A=\frac{1}{2}*b*h

A=\frac{1}{2}*8*10

A=40

Calculation of area of square:

base=width=8

A=8*8

A=64

There are four triangle and five squares on the surface

so, we can find surface area

SA=4* triangle + 5*square

SA=4*40+5*64

SA=480ft^2

so, surface area is 480ft^2.............Answer
