Answer 1

please mark me as brainliest

Answer 2

The altitude of the parallelogram is 25 cm

Step-by-step explanation:

Area of parallelogram top for Rs.20 = 10 sq.cm.

Area of parallelogram top for Rs.2250 =$\frac{10}{20} \times 2250=1125 sq.cm.$

Base of parallelogram = 45 cm

Area of parallelogram = $Base \times Height$

Area of parallelogram =$45 \times Height$

We are given that Area of parallelogram top is 1125 sq.cm.

So, $1125 = 45 \times height$

$\frac{1125}{45}=h$

25 = h

Hence the altitude of the parallelogram is 25 cm
