Find the area of a rectangle with a perimeter of 12 meters and a base of 4 meters
stepladder [879]
Considering the perimeter (P)
p = 2 \times b + 2 \times h
where b is the base and h is the height, then
12 = 2 \times 4 \times 2 \times h \\  \\ h =  \frac{12 - (2 \times 4)}{2}  \\  \\ h = 2
Being the area (A)
a = b \times h \\  \\ a = 4 \times 2 \\  \\ a = 8 {m}^{2}

Natali [406]
5. The 5th figure will have 30 tiles.
6. The 6th figure will have 42 tiles.
7. The pattern is non-linear (quadratic).
8. The 20th figure can be made with 420 tiles.

_____
The Nth figure is made with n*(n+1) tiles. To answer question 8, you must solve
.. n(n +1) = 420
.. n^2 +n -420 = 0
.. (n +21)(n -20) = 0
.. n = 20 or -21 . . . . the negative solution is extraneous
