Question

If the parallel side of parallelogram is 2cm appart and their sum is 12cm then find it's area

Answer 1

Answer:

area of parallelogram =base ×altitude

=2×12cm

= 24cm^2

Answer 2

$\huge{ \underline{ \bf{{{ \pink{ \overline{Solution:}}}}}}}$

Opposite sides of a parallelogram are equal

∴ a + b = 12

a + a = 12

2a = 12

a = 6

We know,

$\longrightarrow \boxed{ \sf{ \red{Area \: of \: parallelogram} \: = \green{\: a \: × \: h}}}$

⇒ 6 × 2

$\implies \bf{12cm ^{2} }$
