Question

If the base and height of a parallelogram are in the ratio 7:3 and the height is 45cm then,find the area of the parallelogram

Answer 1

Step-by-step explanation:

as ratio-7:3

height = 3x

X = 45/3=15

base=7x=15*7

=180cm

Area= base*height

= 45*180

=8100sq.cm

Answer 2

» If the base and height of a parallelogram are in the ratio 7:3 and the height is 45 cm.

• Let base of parallelogram be 7M

and

• Height of parallelogram be 3M

Also given that height of parallelogram = 45 cm

=> 3M = 45

=> M = 45/3

=> M = 15

Base of parallelogram = 3M

=> 7 × 15

=> 105

_______________________________

Area of parallelogram = base × height

=> 105 × 45

=> 4725 cm².

_______________________________

4725 cm² is the area of parallelogram.
