Solve for a. Correct answer gets BRAINLIEST

Mathematics
1 answer:
Darina [25.2K]3 years ago

Hey there!!

Equation given :

A = h ( a + b ) / 2

Multiply by 2 on both sides

2A = h ( a + b )

Divide by h on both sides

2A / h = a + b

Subtract by b on both sides

2A / h - ( b ) = a

Hence, the option ( a ) is the correct answer

Hope my answer helps!

Work out the height of a parallelogram with a base of 10m and an area of 60m2
noname [10]
Area formula of a parallelogram is
        A = base x height

Given are the
Area = 60 m² and base = 10 m

 Substitute the given:

60 = 10h  (divide by 10 to find value of h)
\frac{60}{10} = \frac{10h}{10}  (10 and 10 cancels out)

h = 6
The height of a parallelogram with a base of 10m and an area of 60m² is 6m
