Question

In a parallelogram the altitude is twice the length of base . Its area is 450 cm square. Find the length of base and altitude.​

Answer 1

Answer:

Step-by-step explanation:

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

$hey \: mate \: thank \: for \: the \: question \: \\ hope \: it \: helps \\ let \: the \: base \: of \: parallelogram \: be = \: x \\ so \: altitude \: becomes \: = 2x \\ area \: of \: parallelogram = 450 \\ altitude \times base = 450 \\ x \times 2x = 450 \\ 2x {}^{2} = 450 \\ x {}^{2} = 225 \\ x = \sqrt{225} \\ x = 15 \\ so \: base = x = 15 \\ altitude = 2x = 2 \times 15 = 30$
