Question

: The area of a parallelogram whose altitude is 12cm is 336cm². Determine the corresponding side.​

Answer 1

Answer:

ANSWER

Area of a parallelogram=base×height.

⇒54=15×height

⇒ height=

15

54

=

5

18

=3.6cm

∴ height of the parallelogram=3.6cm

Answer 2

Answer:

Given :

• Area Of Parallelogram = 336 cm²

• Height = 12 cm

To Find :

• Base Of Parallelogram = ? ( corresponding side )

Formula To Find Area :

Area = Base × Height ( b × h )

So,

Base = Area / height

Solution :

Base = Area / Height

b = 336 / 12

b = 28

∴ Base Of Parallelogram = 28 cm

⟶ Area = base × height ( b × h )

⟶ 336 = 28 × 12

⟶ 336 = 336

LHS = RHS

Formulas To Find Area :

• Circle = πr²

r = radius of the circle

• Triangle = ½ × b × h

b = base, h = height

• Square = a ²

a = length of side

• Rectangle = l × b

l = length, b = breadth

• Parallelogram = b × h

b=base, h=vertical height

• Trapezium = ½(a+b) × h

a and b are the length of parallel sides,

h = height
