Question

2) If the base of a parallelogram is 8 cm and it's height is 7 cm, then its area is
(a) 28 sq. cm.
(b) 42 sq. cm.
(c) 56 sq. cm.
(d) 70 sq. cm.

Answer 1

Answer:

c) 56 sq. cm

Step-by-step explanation:

Answer 2

Given : The base of a parallelogram is 8 cm and it's height is 7 cm .

Need To Find : The Area of Parallelogram.

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

⠀⠀⠀⠀⠀Finding Area of Parallelogram :

$\dag\:\cal{As,\:We\:know\:that\::}$

$\qquad \quad \dag\:\:\bigg\lgroup \sf { Area _{(Parallelogram)} = b \times h }\bigg\rgroup$

⠀⠀⠀⠀Here b is the Base of Parallelogram & h is the Height of Parallelogram. ⠀⠀⠀

$\qquad \longmapsto \sf{Area = 8 \times 7 }$

$\qquad \longmapsto \cal{\purple {\underline { Area = 56\:cm^2 }}}$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm {  Area \:of\:Parallelogram \:is\:\bf{56\: cm^2}}}}$
