Question

if length and width of a rectangle are defined as (6+_0.3cm) and (4+_0.6cm) then area of rectangle?​

Answer 1

sorry I don't know the answer

Answer 2

Length = 5.7 ± 0.1 cm

breadth = 3.4 ± 0.2 cm

A = Lb

= (5.7 × 3.4)

= 19.38 cm²

ΔA = A × (ΔL/L + Δb/b)

= 19.38 × (0.1/5.7 + 0.2/3.4)

= 1.48 cm²

Area of rectangle = (19.38 ± 1.48) cm²
