Question #16262

The area of square mirror is 81 sq cm. Pia wants to protect its sides. Allowing 1/2 cm for overlapping he requires tape measuring

Expert's answer

As the area of a mirror is 81 cm² and the mirror is square, then the side length of the mirror is

L = √(81[cm²]) = 9[cm].

So, the required tape measuring is

M = 9[cm] + 0.5[cm] = 9.5[cm].

L = √(81[cm²]) = 9[cm].

So, the required tape measuring is

M = 9[cm] + 0.5[cm] = 9.5[cm].
