Step-by-step explanation:
you could count the squares around the shape or you could do it by points
For example point M is (2,3)
L is (6,3)
We want to find the length of this side so we subtract the x values
6 - 2 = 4 units
that gives use the length of that leg and since a rectangle is symmetrical, you can just measure 2 sides
If BD = 12x + 36
And BD = BC +CD = 3 + 1 = 4
BC = (12x + 36)/4 x 3
= 12(x+ 3) /4 x3
= 3(x+3) x 3
= 9x + 27
Likewise,
FE = 12(x + 3) /3 x 1
= 4x + 12
Area = 1/2 x (BC + FE) x DE
= 1/2 x (9x + 27 + 4x + 12)x (x+1)
= 1/2 x (13x + 39) x (x +1)
= 1/2 x 13x2 + 52x + 39
Hope this helps,

Answer:
the 8th term would be 1,312,500
Step-by-step explanation:
just multiple by 5 eight times
H^2 = x^2 + y^2
where h is the hypotenuse, x and y are the legs.
h = 19cm
x = 12cm.
y = ?
h^2 = x^2 + y^2
y^2 = h^2 - x^2
y^2 = 19^2 - 12^2
y^2 = 361 - 144
y^2 = 217
y = sqrt(217)
y = 14.7
Letter B
