Question

To make a rectangular lawn in front of the school the principal spent

Rs 10x2+ 35x+30 at the rate of Rs 5 per square metre. What is the area of

the lawn? What are its dimensions?​

Answer 1

Step-by-step explanation:

area of the lawn = 10x²+35x+30/5

10x²+20x+15x+30/5

10x(x+2)+15(x+2)/5

(x+2)/5 (10x+15)/5

5(2x+3)/5

x=2.5 (2x+3)

x=1.5
