Question

the area of a parallelogram is 450cm^2 and it's altitude is 20 cm find the length of the Base
​

Answer 1

Answer:

45 cm

Step-by-step explanation:

Area = 450 cm²

Altitude = 20 cm

Since, area of a ║gram = 1/2 ×altitude ×base

Therefore, 1/2 ×20 ×base = 450

10 × base = 450

base= 450/10

base = 45 cm
