Question

the side of a rectangular lamina are (8.5+/- 0.2)cm and (5.6+/-0.1) cm calculate perimeter of lamina within error limits. ​

Answer 1

Answer:

Explanation:

Perimeter = 2(L+B)

ΔP = 2(ΔL + ΔB)

     = 2(0.1+0.2)

     = 0.6

Therefore, the perimeter of the lamina =  2(8.5 + 5.6) ± 0.6 cm

                                                                 = 28.2 ± 0.6 cm

Hope this helps you
