Answer:

h = $\frac{2A}{b}$

Step-by-step explanation:

Area (A) of a triangle = $\frac{1}{2}$ × base (b) × height (h)

i.e A = $\frac{1}{2}$ bh

h = $\frac{2A}{b}$

Pls help me i need to fill in the boxes that dont have anything in them but i aldo need to fill in the one that says "A="

Step-by-step explanation:

$\bf \red { Area: \; \boxed{ 24 } units^2}$

Formula of area of a parallelogram is :

Area of parallelogram = b × h

○ b denotes base

○ h denotes height

Here,

Base of the parallelogram is 6 units and height is 4 units.

→ Area of the parallelogram = 6 units × 4 units

→ Area of the parallelogram = 24 units²

$\therefore$ Area of the parallelogram is 24 units².

$\bf \purple { Perimeter: \; \boxed{ 22 } units}$

Perimeter of parallelogram = Sum of all sides

Since, opposite sides of a parallelogram are equal. So,

○ First side = 6 units

○ Second side = 5 units

○ Third side = 6 units

○ Fourth side = 5 units

→ Perimeter = ( 6 + 5 + 6 + 5 ) units

→ Perimeter = ( 12 + 10 ) units

→ Perimeter = 22 units

$\therefore$ Perimeter of the parallelogram is 22 units.

$\boxed{ \sf { AREA \; FORMULA }}$

$\boxed { \sf { A = Base \times Height }}$

4+7a=12+8a with steps pls

Varvara68 [4.7K]

Answer:a=-8

Step-by-step explanation:

4+7a=12+8a

So first you want to have the variables on the same side

4+7a-7a=12+8a-7a

This is how you got the 7a to the right side. Then you subtract 8a-7a So the equation becomes

4=12+a

Now there are two ways of doing this.

1. 4-12=12-12+a

You moved the 12 to the left side so you have the same variable on one side

4-12=-8

So then a=-8

2. 4-4=12-4+a

0=8+a

then you would have to subtract 8 to keep 'a' by itself

-8=8-8+a

simplify it

-8=a

same thing
