Question

in parallelogram the altitude is twice the length of the base its area is 450 cm squre finde the lenght of base and altitude

Answer 1

Let base = x
Altitude = 2x

Area of parallelogram = b × h
450cm sq. = (x) × (2x)
450cm sq. = 2x^2
450cm sq. ÷ 2= x^2
225cm sq. = x^2
15cm = x

BASE = x = 15cm

ALTITUDE = 2x = 2 × 15cm = 30cm

Answer 2

Let the base be X
so altitude will be = 2 x
AREA= BASE × ALTITUDE
SO
X×2X= 450
2x^2=450
x^2 = 225
x= 15

so base = 15 cm
altitude = 30 cm
