What is the perimeter of the isosceles triangle shown below? If necessary, round to the nearest tenth.

A.
22 units
B.
24 units
C.
36 units
D.
32 units

D. 32 units

Step-by-step explanation:

Isosceles measures 11 + 11 + 10 base.

Area = 32 unit sq

We can double check by creating a vortex and new point 90 degree. This is found at central height line.

base = 5 square 25   12 square 144  (144-25=√119) = 10.91

As we can prove that the matching sides are 10.91

= 10.91 +10.91 +12 = 32 with rounding (= 11 +11 + 10 = 32).

= 32units.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
