Question

 The area of a rectangular plot is 150 sq.m. Its length is 15 m. (a) Find its breadth. (b) Find the cost of levelling the floor at the rate of Rs. 12 per sq.m​

Answer 1

Answer:

Area of rectangle =

$length \times \: breadth$

Substituting the values

$15m \times \: breadth = 150 {m}^{2}$

$\implies \: breadth = \dfrac{150}{15} = 10m$

Coast of leveling

$1 {m}^{2} = 12 \: rupees \\ then$

Coast of leveling

$150 {m}^{2} = 150 \times 12 = 180rupees$
