Question

A rectangular chalkboard is 1.7 m long and 0.9 m wide.

Answer 1

Answer:

$A=1.53\ m^2$

Step-by-step explanation:

The length of a chalkboard, l = 1.7

The width of a chalkboard, b = 0.9 m

We need to find the area of the chalkboard. The formula for the area of a rectangle is given by :

$A=L\times B\\\\A=1.7\times 0.9\\\\A=1.53\ m^2$

So, the area of the chalkboard is equal to $1.53\ m^2$.
