Question

Please tell the answer of question 1 given in above pic

Answer 1

Step-by-step explanation:

1.

As per given in question we have to find distance which means perimeter of rectangle

and formula of

Perimeter of rectangle is = 2(L+B)

but here we only know breadth which is 16 m,

so we have to find length by area formula

Area of rectangle= L× B

So,

$576 = l \times 16$

$l = \frac{576}{16} m = 36m$

so

Perimeter

$= 2(36 + 16)m = 144m$

Hence total distance covered is 144meter.

2.

Area of carpet = (15-2)(10-2)= 13×8 = 104 m^2

Area not covered by carpet = (Area of room) - (Area of carpet)

=(15×10)-104= 46m^2
