Question

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

Answer 1

ANSWER:

8100sq.cm

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

Answer:

4725 sq.cm

Step-by-step explanation:

base : height = 7 : 3

the height is 45 cm

∴ 3x = 45 or, x = 15

and base = 7 x 15 = 105 cm

area = base x height = 45 x 105 = 4725 sq cm
