Question

The area of a parallelogram shaped field is 150 sq. m and it's altitude is 15 m. What is the length of it's base? If one third part of the field has been provided to the government for taking care of covid patients by the owner of the field, which value has been shown by the owner? *​

Answer 1

Step-by-step explanation:

Let the length of the rectangle be l and breath be b

Given, lb=150.........(i)

Also give, 2(l+b)=50

l+b=25

l=25−b ....(ii)

Substituting this value of l in eqn. (i), we get

(25−b)(b)=150

b

2

−25b+150=0

∴b=15 cm, 10 cm

∴ when b=15cm, l=10cm and when b=10cm, then l=15cm.

∴ dimensions of the rectangle are 10,15
