<h3>Area of shape P = 12 square cm</h3>

Explanation:

Shape P is a triangle with the base of 4 units across the horizontal portion up top.

The height of the triangle is 6 units. Count the spaces down the middle of the triangle and you should get 6 spaces.

Area = base*height/2

Area = 4*6/2

Area = 24/2

Area = 12 square cm.

Please can anyone help me on this question information below.
Delvig [45]

Answer:

a) 0.11

b) 60

Step-by-step explanation:

12+35+11+23+7+12 = 100

P(3) = 11/100 = 0.11

P(6) = 12/100 = 0.12

Expected no. of sixes:

500 × 0.12 = 60

the base of a triangle is 11ft more than the height. if the area is 51ft^2 find the base and the height
nekit [7.7K]
So.. notice the picture below

and thus, we also know, that A = 51, thus

\bf A=\cfrac{1}{2}bh\implies A=\cfrac{(h+11)h}{2}\implies A=\cfrac{h^2+11h}{2}\qquad A=51&#10;\\\\\\&#10;51=\cfrac{h^2+11h}{2}\implies 102=h^2+11h\implies 0=h^2+11h-102&#10;\\\\\\&#10;0=(h+17)(h-6)\implies &#10;\begin{cases}&#10;0=h+17\implies &-17=h\\&#10;0=h-6\implies &6=h&#10;\end{cases}

now, the height is just a value, it can't be negative, thus  we can rule out -17, thus h = 6

and surely you'd know what the base is
